Question

Первый насос может накачать 1510 л воды за 2 часа, а второй насос за тоже время может накачать в 3 раза больше. Сколько литров воды могут накачать два насоса за 3 часа совместной работы.

Answer 1

Для выполнения РАБОТЫ применяются такие же формулы, как и для ПУТИ.
1) V1 = 1510 : 2 = 755 л/час - производительность первого насоса.
2) V2 = 3*V1 = 2265 л/час - у второго -  в три раза больше.
Работают вместе
3) Vc = V1+ V2 = 755 + 2265 = 3020 л/ч - совместно.
4) S = Vc*t = 3020 * 3 = 9060 л -  за 3 часа вместе -  ОТВЕТ

Answer 2

1) 1510\2=752
2)752*3=2256
3)2256*3=6768
4)6768+2256=9024
ответ: 9024

Answer 3

Calculation of Water Pump Capacity

To calculate the total amount of water that two pumps can pump in 3 hours, we need to determine the pumping capacity of each pump and then add them together.

Given information: - The first pump can pump 1510 liters of water in 2 hours. - The second pump can pump 3 times more water than the first pump in the same time frame.

Let's calculate the pumping capacity of the second pump: - The first pump can pump 1510 liters of water in 2 hours. - Therefore, the second pump can pump 3 times more water, which is 1510 * 3 = 4530 liters of water in 2 hours.

Now, let's calculate the total amount of water that both pumps can pump in 3 hours: - The first pump can pump 1510 liters of water in 2 hours. - The second pump can pump 4530 liters of water in 2 hours. - In 3 hours, the first pump will pump 1510 * (3/2) = 2265 liters of water. - In 3 hours, the second pump will pump 4530 * (3/2) = 6795 liters of water. - Therefore, the total amount of water that both pumps can pump in 3 hours is 2265 + 6795 = 9060 liters.

So, when working together for 3 hours, the two pumps can pump a total of 9060 liters of water.
