A convoy departed at 08:30 and traveled for 5 hours and 45 minutes. What time did the convoy arrive, in 24-hour military time?
- A14:30
- B14:15
- C15:15
- D13:75
Show answer & explanationAnswer & explanation
Correct answer: B. 14:15
Add the hours and minutes separately. If minutes exceed 60, carry over to the hours. Convert to 24-hour format if necessary.
Why the other options are wrong
- A. This option is incorrect; it might result from incorrect minute addition or carry-over.
- C. This option is incorrect; it might result from a miscalculation in adding hours or minutes.
- D. This option is incorrect; it results from adding minutes directly without converting 75 minutes to 1 hour and 15 minutes.
Time Addition (Military/24-hour)
Adding time in 24-hour format involves summing hours and minutes separately, remembering that minutes 'roll over' at 60, adding to the hours.
- Minutes are base 60, hours are base 24.
- No AM/PM distinction in 24-hour time.
- Carry over minutes exceeding 59 to the hour count.
Memory trick: Think of a clock's hands moving forward, but minutes jump to hours at 60.
