Answer 1

1) 1час или 60 минут
2) 570 минут или же 9часов 30 минут

Answer 2

To convert minutes to hours, you divide the number of minutes by 60, and to convert hours to minutes, you multiply the number of hours by 60. Let's solve each part of the equation step by step:

1. 120 minutes - 1 hour: To convert 1 hour to minutes, we multiply 1 hour by 60 (1 hour = 60 minutes). So, 120 minutes - 60 minutes = 60 minutes.

Now, we have 60 minutes left after subtracting 1 hour from 120 minutes.

2. 9 hours 45 minutes - 15 minutes: To convert 9 hours to minutes, we multiply 9 hours by 60 (9 hours = 9 * 60 minutes = 540 minutes).

Now, we have: 540 minutes + 45 minutes - 15 minutes = 570 minutes.

3. Convert the result back to hours and minutes: To convert 570 minutes back to hours and minutes, we divide 570 by 60. The quotient will be the number of hours, and the remainder will be the number of minutes.

570 minutes ÷ 60 minutes per hour = 9 hours with a remainder of 30 minutes.

So, the final result is 9 hours and 30 minutes.
