Section B: Converting Time (Q9–14, 1 mark each)
Q9. 120 minutes
Method: 1 hour = 60 min, so 2 × 60 = 120.
Q10. 90 minutes
Method: 1 h 30 min = 60 + 30 = 90.
Q11. 3 hours
Method: 180 ÷ 60 = 3.
Q12. 180 minutes
Method: 3 × 60 = 180.
Q13. 255 minutes
Method: 4 × 60 = 240; 240 + 15 = 255.
Q14. 1 hour 30 minutes
Method: 90 = 60 + 30, so 1 h 30 min.
Section C: Word Problems (Q15–20, 2 marks each)

Working: 9:00 to 12:00 = 3 h; 12:00 to 7:00 = 7 h; 3 + 7 = 10 h.
Marks: 1 for method, 1 for answer.
Common mistake: Counting 9 to 7 as 2 hours; remember overnight crosses 12.
