Question

Через 2 часа. После равномерного спуска воды в бассейне её осталось 291 м3, а ещё через 3 часа.- 216 м3. Сколько воды было в бассейне Ответ: _______ м3 было. !!!ПРОШУ СРОЧНО!!!

Answer 1

291 м³ - через 2 часа

216 м³ - ещё через 3 часа

Ск. воды было в бассейне?

- - - - - - - - - - - - - - - - - - - - - - -

1) 291 - 216 = 75 (м³) - спустили за 3 часа;

2) 75 : 3 = 25 (м³) - спускается за 1 час;

3) 25 · 2 = 50 (м³) - спустили за первые 2 часа;

4) 291 + 50 = 341 (м³) - столько воды было в бассейне.

Ответ: 341 м³.

Answer 2

Calculation of Water in the Pool

To calculate the amount of water in the pool, we can use the information provided. After a uniform decrease in water level, there were 291 m3 of water left in the pool after 2 hours, and after an additional 3 hours, there were 216 m3 of water left.

To find the initial amount of water in the pool, we need to determine the rate at which the water level is decreasing. We can do this by finding the difference in water levels over the given time period.

The difference in water levels is 291 m3 - 216 m3 = 75 m3.

Since this difference occurred over a time period of 3 hours, we can calculate the rate of water level decrease as follows:

Rate of water level decrease = Difference in water levels / Time period

Rate of water level decrease = 75 m3 / 3 hours = 25 m3/hour.

Now, we can calculate the initial amount of water in the pool by adding the amount of water left after 3 hours (216 m3) to the product of the rate of water level decrease and the time period (3 hours):

Initial amount of water in the pool = 216 m3 + (25 m3/hour * 3 hours) = 216 m3 + 75 m3 = 291 m3.

Therefore, the initial amount of water in the pool was 291 m3.
