Question

Насос за 7 часов выкачивает b л воды. сколько литров воды он выкачивает за 10 часов?

Answer 1

Ответ:

10b/7

Пошаговое объяснение:за 1час насос выкачивает: b/7, значит за 10часов насос выкачивает:b/7x10=10b/7

Answer 2

To find out how many liters of water the pump can pump in 10 hours, we can set up a proportion based on the information given:

Let's call the number of liters of water pumped in 10 hours as "x" liters.

The rate of water pumped by the pump is constant, so we can use the formula:

Rate = Amount of water / Time

From the given information, we have: Rate = b liters / 7 hours

Now, we can set up the proportion:

Rate in 10 hours / Rate in 7 hours = Amount of water in 10 hours / Amount of water in 7 hours

x liters / 10 hours = b liters / 7 hours

To find x, we can cross-multiply and solve for x:

x = (b liters / 7 hours) * 10 hours

x = (10/7) * b liters

Now, we can calculate the value of x:

x = (10/7) * b

So, the pump can pump (10/7) times the amount of water it pumps in 7 hours in 10 hours.
