Question

Обрі 57. 1) Емкость бассейна 620 м". Из двух кранов поступает вода. Из 70 м. За сколько часов наполнится весь бассейн, если вода первого крана поступает за час 85 м воды, а из второго крана - поступает из двух кранов одновременно? 26

Answer 1

Ответ:

Пошаговое объяснение:

1. 620-70=550

2. 550-80=470

Answer 2

To find the time it takes to fill the entire pool, we need to calculate the combined flow rate of water from both taps and then divide the total capacity of the pool by the flow rate.

Given: - Capacity of the pool: 620 m³ - Flow rate of the first tap: 85 m³/h - Flow rate of the second tap: 70 m³/h

To find the combined flow rate, we add the flow rates of both taps: Combined flow rate = Flow rate of the first tap + Flow rate of the second tap

Let's calculate the combined flow rate: Combined flow rate = 85 m³/h + 70 m³/h = 155 m³/h

Now, we can find the time it takes to fill the pool by dividing the pool's capacity by the combined flow rate: Time = Capacity of the pool / Combined flow rate

Let's calculate the time: Time = 620 m³ / 155 m³/h = 4 hours

Therefore, it will take 4 hours to fill the entire pool when water is flowing from both taps simultaneously.
