Answer:
D.
Step-by-step explanation:
So we just need to raise the pool back to original level
in total, the pool drained a total of 1 and 3/8 inches
so we need to find out how long it would take to raise the pool by 1 and 3/8 inches
1 inch=320 gallons
1 and 3/8=320 times 1 and 3/8=320 and 960/8=440
he needs to put in 440 gallons
it is 5.75 gallons per minute
find out how many minutes it will take
440=5.75 times x minutes
divide both sides by 5.75
76.521=xminutes
round
77 minutes
1 hour=60 minutes
77>60
it will take more than 1 hour to make the pool back to original level
