Answer 2

1 час = 60 мин

400мин -5ч 20 мин =​ 400 мин - 5*60 +20 мин = 400 мин - 320 мин = 80 мин= 1 час 20 мин

Answer 3

To subtract 5 hours and 20 minutes from 400 minutes, we need to convert the hours to minutes and then perform the subtraction:

1 hour = 60 minutes

5 hours = 5 * 60 = 300 minutes

Now, subtract 300 minutes (5 hours) and 20 minutes from 400 minutes:

400 minutes - 300 minutes - 20 minutes = 80 minutes

So, 400 minutes - 5 hours and 20 minutes = 80 minutes.
