Sample Problem

Find the time with the 24-hour clock. Give your answer in the 24-hour clock form, for example, 15:00.

A concert started at 21:45. If the concert lasted 3 h 5 minutes, at what time did the concert end?

 

Solution

Start time: 21:45

Elapsed time: 3 h 5 min

End time: 21:45 + 3 h 5 min = 00:50

So the answer is 00:50.
