Answer 2

15ч 20мин - 9ч 55мин =14 ч 80 мин. -9 ч 55 мин =14 ч 80 мин- 9 ч55 мин =5ч25 мин

Answer 3

To subtract 9 hours and 55 minutes from 15 hours and 20 minutes, you need to subtract the hours and minutes separately.

Subtracting the minutes first:

20 minutes - 55 minutes = -35 minutes

Since we have a negative result, we need to borrow 1 hour (60 minutes) from the hours portion.

Subtracting the hours:

15 hours - 9 hours - 1 hour = 5 hours

Putting it back together:

5 hours - 35 minutes = 4 hours and 25 minutes

Therefore, 15 hours and 20 minutes minus 9 hours and 55 minutes is 4 hours and 25 minutes.
