Каков объём бассейна? Пжпжпжппжпжпжпжжпжппж помогите дам максимум баллов!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

Answer 1

Ответ:

17010. литров Всё в фото

Answer 2

Ответ:

1.25*40 = 50 л. поступает за одну минуту из второй трубы

90+40 = 90 л из двух труб за 1 мин

3,15*60 = 189 мин

90 л/мин *189 мин = 17010 л

Problem Analysis

We are given that water is being filled into a pool from two pipes simultaneously for a duration of 3.15 hours. The first pipe fills 40 liters of water per minute, while the second pipe fills 1.25 times more water in the same amount of time. We need to find the volume of the pool.

Calculation

To find the volume of the pool, we need to calculate the total amount of water filled by both pipes and multiply it by the duration of filling.

Let's calculate the amount of water filled by each pipe in 3.15 hours:

- The first pipe fills 40 liters of water per minute. So, in 3.15 hours, it will fill: - 40 liters/minute * 60 minutes/hour * 3.15 hours = 7560 liters

- The second pipe fills 1.25 times more water than the first pipe in the same amount of time. So, in 3.15 hours, it will fill: - 1.25 * 40 liters/minute * 60 minutes/hour * 3.15 hours = 9450 liters

Now, let's calculate the total volume of the pool by adding the amounts of water filled by both pipes:

- Total volume = volume filled by the first pipe + volume filled by the second pipe - Total volume = 7560 liters + 9450 liters = 17010 liters

Therefore, the volume of the pool is 17010 liters.

Answer

The volume of the pool is 17010 liters.
