Question

Два насоса заполняют бассейн объемом 18000 л за 150 минут. Из первого насоса за минуту вытекает 70 л воды.Сколько литров вытекает из второго насоса?

Answer 1

18000:150=120 (л) воды вытекает из двух насосов за 1 минуту

120-70=50 (л) воды вытекает из второго насоса в минуту

Ответ: 50 литров.

Answer 2

A=V/t

A=18000:150=120л/мин

A2=A-A1=120-70=50л/мин

Ответ:50л/мин

Answer 3

To solve this problem, we need to find the flow rate of the second pump. We know that the combined flow rate of both pumps is filling the pool at a rate of 18000 liters in 150 minutes.

Let x be the flow rate of the second pump (in liters per minute).

Flow rate of the first pump: 70 liters per minute Flow rate of the second pump: x liters per minute

The combined flow rate of both pumps is the sum of their individual flow rates:

Flow rate of both pumps = Flow rate of the first pump + Flow rate of the second pump 18000 liters / 150 minutes = 70 liters/minute + x liters/minute

Now, let's solve for x:

x = (18000 liters / 150 minutes) - 70 liters/minute x = 120 liters/minute - 70 liters/minute x = 50 liters/minute

So, the flow rate of the second pump is 50 liters per minute.
