Question

6 насосов заполняет бак за 8 часов.чколько насосов заполнят тотже бак за 3 часа

Answer 1

Ответ:

16 насосов

Пошаговое объяснение:

6 нас.   -  8ч

х нас.    -   3ч

х=6*8/3

х=16 насосов

но я не уверена в правильности ответа

Answer 2

6 насосов - за 8 часов
? насосов - за 3 часа

1) 8:3=8/3=2цел. 2/3 (раза)- меньше затрачено времени.
2) 6•2цел. 2/3=6•8/3=48/3=16 (насосов) - заполнят бак за 3 часа.
Ответ: 16 насосов заполнят бак за 3 часа.

Answer 3

To find out how many pumps are needed to fill the tank in 3 hours, we can use the concept of work rates.

Let's assume the capacity of the tank is C (you can use any unit of volume like liters, gallons, etc.) and the efficiency of each pump is the same.

We know that 6 pumps can fill the tank in 8 hours, so their combined work rate is:

Work rate of 6 pumps = 1 tank / 8 hours = 1/8

Now, we need to calculate how many pumps are needed to fill the same tank in 3 hours. Let's call the number of pumps required as "x."

Work rate of x pumps = 1 tank / 3 hours = 1/3

Since the efficiency of each pump is the same, we can set up a proportion:

(Work rate of 6 pumps) / (Work rate of x pumps) = (Number of pumps) / (Number of pumps required)

(1/8) / (1/3) = 6 / x

To solve for x, cross-multiply:

(1/8) * x = (1/3) * 6

x = (1/3) * 6 * 8

x = 16

So, 16 pumps are needed to fill the tank in 3 hours.
