Question

в бассейн из двух труб вливается вода. из одной трубы со скоростью 37 л\мин из другой - 42 л\мин за какое время заполнится этот бассейн который вмещает 31200 л воды если в нем есть сток откуда выливается 14 литров воды.

Answer 1

1) 37 +42= 79 литров вливается
воды
2) 79-14 =65 л воды в мин
наполняет басейн
3)31200 :65 =480 мин
480мин= 8часов
ответ:за 8часов

Answer 2

Calculating the time to fill the pool

To calculate the time it takes to fill the pool, we need to determine the net inflow rate of water into the pool. This can be calculated by subtracting the outflow rate (water being drained from the pool) from the total inflow rate (water being poured into the pool).

Given: - Inflow rate from one pipe: 37 liters per minute - Inflow rate from the other pipe: 42 liters per minute - Outflow rate from the drain: 14 liters per minute - Pool capacity: 31,200 liters

To find the net inflow rate, we subtract the outflow rate from the total inflow rate:

Net inflow rate = (Inflow rate from one pipe) + (Inflow rate from the other pipe) - (Outflow rate from the drain)

Net inflow rate = 37 + 42 - 14 = 65 liters per minute

Now, we can calculate the time it takes to fill the pool by dividing the pool capacity by the net inflow rate:

Time to fill the pool = (Pool capacity) / (Net inflow rate)

Time to fill the pool = 31,200 / 65 = 480 minutes

Therefore, it will take approximately 480 minutes to fill the pool.
