the pump to fill the pool?


I know it’s really late at now or early in the morning but can someone plz help me on this plz

Answer 1

Im pretty sure the answer is 5 hours

Explanation:

The capacity of swimming pool is

v = 10 ⋅ 8 ⋅ 5 = 400 cubic feet

The pump fills 80 cubic feet in 1 hour

Therefore, the pump will fill

400 cubic feet in 5 hours.

Answer 2

9514 1404 393

Answer:

5 hours

Explanation:

The volume of the pool is ...

V = LWH

V = (10 ft)(8 ft)(5 ft) = 400 ft^3

At the given fill rate, the time it will take is ...

(400 ft^3)/(80 ft^3/h) = 5 h

It will take 5 hours for the pump to fill the pool.
