Question

9 ч 10 мин-3 ч 40 мин=

Answer 1

Ответ: 5 часов 30 минут

Пошаговое объяснение:

9*60 =540 минут

540+10=550 минут

3*60 =180 минут

180+40=220 минут

550-220=330 минут

330/60= 5,5часов

0,5*60=30 минут

Answer 2

To subtract the two time durations, you need to perform the subtraction separately for hours and minutes.

9 hours 10 minutes - 3 hours 40 minutes

Subtracting hours: 9 hours - 3 hours = 6 hours

Subtracting minutes: 10 minutes - 40 minutes = -30 minutes

Since we have a negative value for minutes, we need to borrow 1 hour from the 6 hours to compensate for the negative minutes:

6 hours - 1 hour = 5 hours

The final result is 5 hours and -30 minutes, which can be simplified to 4 hours and 30 minutes (by adding the borrowed hour back):

5 hours - 30 minutes = 4 hours 30 minutes.

So, 9 hours 10 minutes - 3 hours 40 minutes = 4 hours 30 minutes.
