Answer Key: Primary 6 PSLE Mathematics Quiz - Speed Distance Time

Total Marks: 50

Section A: Multiple-Choice Questions (Questions 1 to 5)

Each question carries 2 marks.

Answer: B) 60 km/h
Working: Speed = Distance ÷ Time = 180 km ÷ 3 h = 60 km/h
Explanation: The formula for average speed is total distance divided by total time. Here, the car covers 180 kilometres in 3 hours, so we divide 180 by 3 to get 60 km/h.
Common Mistake: Students might multiply 180 by 3 (getting 540 km/h) instead of dividing.

Answer: C) 30 km
Working: Distance = Speed × Time = 15 km/h × 2 h = 30 km
Explanation: To find the distance travelled, multiply the speed by the time. The cyclist rides at 15 km/h for 2 hours, so the distance is 15 × 2 = 30 km.
Common Mistake: Students might divide 15 by 2 (getting 7.5 km) instead of multiplying.

Answer: C) 2.5 hours
Working: Time = Distance ÷ Speed = 180 km ÷ 72 km/h = 2.5 hours
Explanation: To find the time taken, divide the distance by the speed. The train travels 180 km at 72 km/h, so the time is 180 ÷ 72 = 2.5 hours.
Common Mistake: Students might forget to convert the decimal to hours and minutes. 2.5 hours is 2 hours 30 minutes.

Answer: B) 15 minutes
Working: Time = Distance ÷ Speed = 1 km ÷ 4 km/h = 0.25 hours. 0.25 hours × 60 minutes/hour = 15 minutes.
Explanation: First, find the time in hours: 1 ÷ 4 = 0.25 hours. Then convert hours to minutes by multiplying by 60: 0.25 × 60 = 15 minutes.
Common Mistake: Students might think 0.25 hours is 25 minutes, but it is actually 15 minutes (¼ of an hour).

Answer: C) 90 km
Working: Time = 1 hour 30 minutes = 1.5 hours. Distance = Speed × Time = 60 km/h × 1.5 h = 90 km.
Explanation: First, convert the time to hours. 1 hour 30 minutes is 1.5 hours. Then multiply the speed (60 km/h) by the time (1.5 h) to get the distance: 60 × 1.5 = 90 km.
Common Mistake: Students might forget to convert minutes to hours and use 1.3 instead of 1.5.

Section B: Short-Answer Questions (Questions 6 to 15)

Each question carries 3 marks. 1 mark for correct formula/concept, 1 mark for correct substitution, 1 mark for correct final answer with units.

Answer: 40.5 km
Working: Time = 45 minutes = 45/60 hours = 0.75 hours. Distance = Speed × Time = 54 km/h × 0.75 h = 40.5 km.
Explanation: Convert 45 minutes to hours by dividing by 60 (45/60 = 0.75). Then multiply the speed (54 km/h) by the time (0.75 h) to find the distance.
Marking: 1 mark for converting time to 0.75 h, 1 mark for correct multiplication, 1 mark for correct answer with unit.

Answer: 5 m/s
Working: Speed = Distance ÷ Time = 400 m ÷ 80 s = 5 m/s.
Explanation: The runner covers 400 metres in 80 seconds. To find the speed in m/s, divide the distance in metres by the time in seconds.
Marking: 1 mark for correct formula, 1 mark for correct substitution, 1 mark for correct answer with unit.

Answer: 60 km/h
Working: Speed = Distance ÷ Time = 240 km ÷ 4 h = 60 km/h.
Explanation: The lorry travels 240 km in 4 hours. Divide the distance by the time to find the average speed.
Marking: 1 mark for correct formula, 1 mark for correct substitution, 1 mark for correct answer with unit.

Answer: 180 km
Working: Time = 2 hours 15 minutes = 2 + 15/60 = 2.25 hours. Distance = Speed × Time = 80 km/h × 2.25 h = 180 km.
Explanation: Convert 15 minutes to 0.25 hours (15/60 = 0.25). So total time is 2.25 hours. Multiply speed (80 km/h) by time (2.25 h) to get distance.
Marking: 1 mark for converting time to 2.25 h, 1 mark for correct multiplication, 1 mark for correct answer with unit.

10.

Answer: 3 hours 0 minutes
Working: Time = Distance ÷ Speed = 150 km ÷ 50 km/h = 3 hours.
Explanation: Divide the distance (150 km) by the speed (50 km/h) to find the time. 150 ÷ 50 = 3 hours exactly.
Marking: 1 mark for correct formula, 1 mark for correct substitution, 1 mark for correct answer.

11.

Answer: 25 minutes
Working: Time = Distance ÷ Speed = 30 km ÷ 72 km/h = 5/12 hours. 5/12 hours × 60 minutes/hour = 25 minutes.
Explanation: First, find the time in hours: 30 ÷ 72 = 5/12 hours. Then convert to minutes by multiplying by 60: (5/12) × 60 = 25 minutes.
Marking: 1 mark for correct formula, 1 mark for correct conversion to minutes, 1 mark for correct answer.

12.

Answer: 120 km/h
Working: Time = 2 hours 30 minutes = 2.5 hours. Speed = Distance ÷ Time = 300 km ÷ 2.5 h = 120 km/h.
Explanation: Convert 2 hours 30 minutes to 2.5 hours. Then divide the distance (300 km) by the time (2.5 h) to find the speed.
Marking: 1 mark for converting time to 2.5 h, 1 mark for correct division, 1 mark for correct answer with unit.

13.

Answer: 80 km/h
Working: Time = 2 hours 15 minutes = 2.25 hours. Speed = Distance ÷ Time = 180 km ÷ 2.25 h = 80 km/h.
Explanation: Convert 2 hours 15 minutes to 2.25 hours. Then divide the distance (180 km) by the time (2.25 h) to find the average speed.
Marking: 1 mark for converting time to 2.25 h, 1 mark for correct division, 1 mark for correct answer with unit.

14.

Answer: 16 km
Working: Time = 1 hour 20 minutes = 1 + 20/60 = 1 ⅓ hours = 4/3 hours. Distance = Speed × Time = 12 km/h × (4/3) h = 16 km.
Explanation: Convert 20 minutes to ⅓ hour (20/60 = ⅓). So total time is 1 ⅓ hours, which is 4/3 hours. Multiply speed (12 km/h) by time (4/3 h): 12 × 4/3 = 16 km.
Marking: 1 mark for converting time to 4/3 h, 1 mark for correct multiplication, 1 mark for correct answer with unit.

15.

Answer: 24 minutes
Working: Time = Distance ÷ Speed = 2 km ÷ 5 km/h = 0.4 hours. 0.4 hours × 60 minutes/hour = 24 minutes.
Explanation: First, find the time in hours: 2 ÷ 5 = 0.4 hours. Then convert to minutes by multiplying by 60: 0.4 × 60 = 24 minutes.
Marking: 1 mark for correct formula, 1 mark for correct conversion to minutes, 1 mark for correct answer.

Section C: Problem-Solving Questions (Questions 16 to 20)

Each question carries 4 marks. 1 mark for correct concept/strategy, 1 mark for correct working, 1 mark for correct intermediate step, 1 mark for correct final answer with units.

16.

Answer: 40 km
Working:
- Distance travelled by car = 80 km/h × 2 h = 160 km
- Distance travelled by lorry = 60 km/h × 2 h = 120 km
- Distance apart = 160 km - 120 km = 40 km
Explanation: Since they start from the same point and travel in the same direction, the distance between them is the difference in the distances they travel. Find each distance by multiplying speed by time, then subtract.
Marking: 1 mark for finding car's distance, 1 mark for finding lorry's distance, 1 mark for correct subtraction, 1 mark for correct answer with unit.
Common Mistake: Students might add the distances instead of subtracting, thinking they are travelling in opposite directions.

17.

Answer: 10 m/s
Working: Speed = Distance ÷ Time = 300 m ÷ 30 s = 10 m/s.
Explanation: When a train passes a stationary signpost, the distance it travels is equal to its own length. So the train travels 300 m in 30 seconds. Divide distance by time to find speed.
Marking: 1 mark for recognising distance = train length, 1 mark for correct formula, 1 mark for correct substitution, 1 mark for correct answer with unit.
Common Mistake: Students might not understand that the distance is the length of the train.

18.

Answer: 2 hours 0 minutes
Working:
- Distance from Town P to Town Q = 60 km/h × 2.5 h = 150 km
- Time for return journey = 150 km ÷ 75 km/h = 2 hours
Explanation: First, find the distance between the towns using the outward journey: speed (60 km/h) × time (2.5 h) = 150 km. The return journey covers the same distance but at a different speed. Divide the distance (150 km) by the return speed (75 km/h) to find the time.
Marking: 1 mark for finding distance, 1 mark for correct formula for return time, 1 mark for correct division, 1 mark for correct answer.
Common Mistake: Students might forget to convert 2 hours 30 minutes to 2.5 hours.

19.

Answer: 10 00
Working:
- Let the time taken by the car to catch up be t hours after 09 00.
- Distance travelled by bus = 72 km/h × (t + 0.5) h (since bus started 0.5 hours earlier)
- Distance travelled by car = 90 km/h × t h
- When car catches up, distances are equal: 72(t + 0.5) = 90t
- 72t + 36 = 90t
- 36 = 18t
- t = 2 hours
- Time = 09 00 + 2 hours = 11 00
Explanation: The bus has a 30-minute head start. In that time, it travels 72 km/h × 0.5 h = 36 km. The car is faster by 90 - 72 = 18 km/h. The time needed to close the gap is 36 km ÷ 18 km/h = 2 hours. So the car catches up at 09 00 + 2 hours = 11 00.
Marking: 1 mark for recognising the head start, 1 mark for setting up equation or finding the gap, 1 mark for solving for time, 1 mark for correct final time.
Common Mistake: Students might forget to account for the bus's head start.

20.

Answer: 65 km
Working:
- First part: Time = 30 minutes = 0.5 hours. Distance = 40 km/h × 0.5 h = 20 km
- Second part: Time = 45 minutes = 0.75 hours. Distance = 60 km/h × 0.75 h = 45 km
- Total distance = 20 km + 45 km = 65 km
Explanation: The journey has two parts with different speeds. Convert each time to hours, find the distance for each part by multiplying speed by time, then add the distances together.
Marking: 1 mark for converting first time to 0.5 h, 1 mark for finding first distance, 1 mark for finding second distance, 1 mark for correct total distance with unit.
Common Mistake: Students might add the speeds and times together incorrectly instead of finding each distance separately.
