Answer:
Im pretty sure the answer is 5 hours
Step-by-step 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.
9514 1404 393
5 hours
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.
