Question

Elapsed time was 9 hours and 45 min that ended at 6:00 what was the starting time

Answer 1

The answer is 9:15 because if you go ahead and subtract the 6 hours from 9 hours you only have 3 hours left. So 12, 11, 10. Now you have to take 45 minutes from 10:00 so that's 9:15

Answer 2

8:15 is the answer assuming the clock is at PM.
