Answer 1

Половина 9 это 8:30  Маша - 13: 20 - 8: 30 отнять не можем поэтому занимаем 60 минут и так 13 : 20 добовляем к 20 минутам 60 и получается 80 и остаётся 12 часов  получается  12 : 80 - 8:30 =4 часа 50 мин провела Маша в школе Мишу считаем также поэтому  12 : 50 - 8: 30=4 часа 20 минут

Answer 2

Calculating Time Spent in School

To calculate the time the children spent in school, we can use the information provided.

The children arrived at school at half past nine, which is 9:30 AM. When they left, Masha looked at the clock and it was 13:20 (1:20 PM), and Vasya looked at the clock and it was 12:50 PM.

To find out how much time they spent in school, we can subtract the time they arrived from the time they left.

Masha's Time Spent in School: - Masha arrived at 9:30 AM and left at 1:20 PM. - Time spent = 1:20 PM - 9:30 AM = 3 hours and 50 minutes.

Vasya's Time Spent in School: - Vasya arrived at 9:30 AM and left at 12:50 PM. - Time spent = 12:50 PM - 9:30 AM = 3 hours and 20 minutes.

So, Masha spent 3 hours and 50 minutes in school, and Vasya spent 3 hours and 20 minutes in school.
