Answer 1

Ответ:

1Г 2В. 3Г. 4В

Пошаговое объяснение:

1. 45*3=135 це 2 години 15хв.

плюс 3часа басейн буде 5год15хв

2. Т.к. заняття у Катрусі чередуються, то за два дні поспіль вона не потрапила на одне заняття з музиці та на одне з басейну. Разом 1год 45хв. Тож усього за цей тиждень вона займалася 5г15хв-1г45хв= 3г30хв

3. Вона пропустила або 2г45хв, або 2г30 тож усього тоді она займалась або 2г30хв або 2г45хв

Answer 2

Task 3:

On Monday, Wednesday, and Friday, Katrusya attends music school for 45 minutes, while on Tuesday, Thursday, and Saturday, she goes to the swimming pool for one hour. We need to calculate the total time Katrusya spends on her activities during the week.

To solve this, we can add up the time spent at music school and the time spent at the swimming pool.

The time spent at music school is 45 minutes per session, and she attends music school on three days: Monday, Wednesday, and Friday. So the total time spent at music school is 45 minutes x 3 days = 135 minutes.

The time spent at the swimming pool is one hour per session, and she goes to the swimming pool on three days: Tuesday, Thursday, and Saturday. Since there are 60 minutes in an hour, the total time spent at the swimming pool is 60 minutes x 3 days = 180 minutes.

To find the total time Katrusya spends on her activities during the week, we add the time spent at music school and the time spent at the swimming pool: 135 minutes + 180 minutes = 315 minutes.

Therefore, Katrusya spends a total of 315 minutes on her activities during the week.

Task 2:

In one week, Katrusya was sick for two consecutive days. We need to calculate how much time she spent on her activities during that week.

Since she was sick for two days, she did not attend music school or go to the swimming pool on those days. Therefore, we need to subtract the time she would have spent on her activities on those two days from the total time.

The time spent at music school is 45 minutes per session, and she attends music school on three days. So the time spent at music school on a regular week is 45 minutes x 3 days = 135 minutes.

The time spent at the swimming pool is one hour per session, and she goes to the swimming pool on three days. So the time spent at the swimming pool on a regular week is 60 minutes x 3 days = 180 minutes.

Since she was sick for two days, we subtract the time she would have spent on her activities on those two days: 135 minutes + 180 minutes - (45 minutes x 2 days) = 135 minutes + 180 minutes - 90 minutes = 225 minutes.

Therefore, Katrusya spent a total of 225 minutes on her activities during the week when she was sick for two consecutive days.

Task 3:

In this task, Katrusya was sick for three consecutive days. We need to calculate how much time she spent on her activities during that week.

Since she was sick for three days, she did not attend music school or go to the swimming pool on those days. Therefore, we need to subtract the time she would have spent on her activities on those three days from the total time.

The time spent at music school is 45 minutes per session, and she attends music school on three days. So the time spent at music school on a regular week is 45 minutes x 3 days = 135 minutes.

The time spent at the swimming pool is one hour per session, and she goes to the swimming pool on three days. So the time spent at the swimming pool on a regular week is 60 minutes x 3 days = 180 minutes.

Since she was sick for three days, we subtract the time she would have spent on her activities on those three days: 135 minutes + 180 minutes - (45 minutes x 3 days) = 135 minutes + 180 minutes - 135 minutes = 180 minutes.

Therefore, Katrusya spent a total of 180 minutes on her activities during the week when she was sick for three consecutive days.
