Question

Насос выкачивает 5 целых семь девятых литров в минуту. За какое время он выкачает 104 литра?

Answer 1

Преобразуем в дробь 5 7/9=52/9
разделим 104 литра на дробь 104/(52/9)=18 минут
Насос выкачает 104 литра за 18 минут

Answer 2

Calculation of Pumping Time

To calculate the time it takes for the pump to pump 104 liters, we can use the given pumping rate of 5 and 7/9 liters per minute.

Given: - Pumping rate = 5 and 7/9 liters per minute - Volume to be pumped = 104 liters

We can use the formula: time = volume / rate

Substituting the given values: time = 104 / (5 and 7/9)

Calculation

Using the given pumping rate of 5 and 7/9 liters per minute, the time it takes to pump 104 liters can be calculated as follows:

time = 104 / (5 and 7/9) time = 104 / 5.7777... time ≈ 18 minutes

So, it will take approximately 18 minutes for the pump to pump 104 liters.
