Answer 2

Переведем в минуты: Планировала на дз потратить 2 часа 21 минуту (2*60+21=141 минута), потратила на 1 час 18 минут больше (60+18=78 минут), то есть всего потратила 141+78=219 минут=3часа 39 минут

На кино потратила на 1час42 минуты (60+42=102) меньше чем на дз

то есть 219-102=117 минут на кино это 1 час 57 минут

Answer 3

To solve this problem, we need to find the total time spent by the student on homework and watching a movie. Let's break down the information given:

- The student planned to spend 1 7/20 hours on homework. - However, she ended up spending 1 6/20 hours more than planned on homework. - She spent 1 14/20 hours less on watching a movie than on homework.

Let's calculate the total time spent by the student on homework and watching a movie.

Time spent on homework:

The student planned to spend 1 7/20 hours on homework. But she ended up spending 1 6/20 hours more than planned on homework.

To find the actual time spent on homework, we can add the planned time and the extra time spent: 1 7/20 + 1 6/20 = 1 13/20 hours

Time spent on watching a movie:

The student spent 1 14/20 hours less on watching a movie than on homework.

To find the actual time spent on watching a movie, we can subtract the time difference from the time spent on homework: 1 13/20 - 1 14/20 = -1/20 hours

Since the result is negative, it means the student spent less time watching a movie than on homework.

Total time spent:

To find the total time spent by the student on homework and watching a movie, we can add the time spent on homework and the time spent on watching a movie: 1 13/20 + (-1/20) = 1 12/20 hours

Therefore, the student spent a total of 1 12/20 hours on homework and watching a movie.
