Answer 3

To calculate the difference between 15 hours 38 minutes and 7 hours 42 minutes, you simply subtract the two times:

(15 hours 38 minutes) - (7 hours 42 minutes)

Step 1: Convert everything to minutes for easier calculation. 15 hours * 60 minutes/hour = 900 minutes 38 minutes = 38 minutes 7 hours * 60 minutes/hour = 420 minutes 42 minutes = 42 minutes

Step 2: Subtract the minutes. (900 minutes + 38 minutes) - (420 minutes + 42 minutes) = 938 minutes - 462 minutes = 476 minutes.

Step 3: Convert the minutes back to hours and minutes. 476 minutes ÷ 60 minutes/hour = 7 hours with a remainder of 56 minutes.

So, the difference between 15 hours 38 minutes and 7 hours 42 minutes is 7 hours 56 minutes.
