Пошаговое объяснение:

Answer 2

To subtract the two times:

9 hours - 2 hours = 7 hours

12 minutes - 28 minutes = -16 minutes

Since the minutes in the second time (2 hours 28 minutes) are greater than the minutes in the first time (9 hours 12 minutes), we have to borrow an hour and add 60 minutes to the first time:

9 hours - 1 hour = 8 hours

12 minutes + 60 minutes = 72 minutes

Now, we can subtract the two times:

8 hours - 2 hours = 6 hours

72 minutes - 28 minutes = 44 minutes

So, the result is 6 hours and 44 minutes.
