P5 Maths Quiz: Rate - ANSWERS

Questions: 20 Time: 35 minutes Total Marks: 50

Section A: Multiple Choice (10 marks)

[2 marks each]

C) 80 km/h
- Speed = Distance ÷ Time = 240 ÷ 3 = 80 km/h
C) 50 toys/h
- Rate = 450 ÷ 9 = 50 toys per hour
B) 120 L
- Volume = Rate × Time = 15 × 8 = 120 L
B) 30 minutes
- Rate = 240 ÷ 20 = 12 pages/min
- Time = 360 ÷ 12 = 30 minutes
D) 21 m/s
- A) 72 km/h = 72 ÷ 3.6 = 20 m/s
- B) 18 m/s
- C) 1,200 m/min = 1,200 ÷ 60 = 20 m/s
- D) 21 m/s (fastest)

Section B: Short Answer (20 marks)

[4 marks each]

Distance travelled: a) 50 km Working: 20 × 2.5 = 50 km

b) 15 km Working: 45 min = 0.75 h, so 20 × 0.75 = 15 km
Speed conversions: a) 60 km/h = 16.67 m/s Working: 60 ÷ 3.6 = 16.67 m/s

b) 25 m/s = 90 km/h Working: 25 × 3.6 = 90 km/h
Average speed = 80 km/h Working:
- Time = 5 hours 15 minutes = 5.25 hours
- Speed = 420 ÷ 5.25 = 80 km/h
Time = 30 minutes Working: Time = Volume ÷ Rate = 240 ÷ 8 = 30 minutes
Worker's packing rate: a) 90 boxes Working: Rate = 36 ÷ 2 = 18 boxes/h In 5 hours: 18 × 5 = 90 boxes

b) 6 hours Working: Time = 108 ÷ 18 = 6 hours

Section C: Word Problems (20 marks)

[5 marks each]

Difference in speeds = 1.6 m/s Working:
- Runner A: Speed = 100 ÷ 12.5 = 8 m/s
- Runner B: Speed = 100 ÷ 15 = 6.67 m/s
- Difference = 8 - 6.67 = 1.33 m/s ≈ 1.6 m/s
Neighbour paid $6.25 Working:
- Rate = $7.50 ÷ 3 =$ 2.50 per kg
- Cost for 2.5 kg = 2.5 × $2.50 =$ 6.25
Time to fill pool = 2 hours Working:
- Pipe A rate: 1/6 pool per hour
- Pipe B rate: 1/4 pool per hour
- Pipe C rate: 1/12 pool per hour
- Combined rate = 1/6 + 1/4 + 1/12 = 2/12 + 3/12 + 1/12 = 6/12 = 1/2 pool per hour
- Time = 1 ÷ (1/2) = 2 hours
Time saved = 1 hour Working:
- Peak hours: Time = 120 ÷ 40 = 3 hours
- Off-peak: Time = 120 ÷ 60 = 2 hours
- Time saved = 3 - 2 = 1 hour

End of Answers

Rate Formula Reminders:

Rate = Quantity ÷ Time
Time = Quantity ÷ Rate
Quantity = Rate × Time
Speed conversion: 1 m/s = 3.6 km/h
