If I put something in in a place at 1:25 pm and remove it at 10:30 pm how long was, it there

Answer: 9 hours and 5 minutes

Step-by-step explanation:

Take the starting time and minus the end time. 1:25 = 1.25 10:30 = 10.3

10.3 - 1.25 = 9.05, or 9 hours and 5 minutes.

Checking the work: 1:25 + 9 hours = 10:25

10:25 + 5 minutes = 10:30
