Question: 66

10. A group left on a trip at 8:50 a.m. and reached its destination at 3:30 p.m. How long, in hours and minutes, did the trip take

  • A. 3 hours 10 minutes
  • B. 4 hours 40 minutes
  • C. 5 hours 10 minutes
  • D. 6 hours 40 minutes

Correct Answer: D

Explanation:

The correct answer is (D). First convert to a 24-hour clock.

3:30 p.m. = 15:30 o'clock

15:30 = 14:90

- 8:50 = -8:50

6:40 = 6 hours 40 minutes

To subtract a larger number of minutes from a smaller number of minutes, borrow 60 minutes from the hour to enlarge the smaller number.
