C.
10 h
D.
25 hi think the answer might be C

Answer 1

First you need to find the amount of gallons per hour
1000 ÷ 4 = 250
then divide that by the amount of gallons you want to find (2500)
2500 ÷ 250 = 10
the answer is C. 10 hours

Answer 2

Option C.
`10\ hours`

Explanation:

we know that

A pipe can pump
`1000` gallons of water in
`4` hours

so

by proportion

Find how long would it take the pipe to fill a
`2500` gallon pool

`(4)/(1,000)(hours)/(gallons) =(x)/(2,500)(hours)/(gallons)\\ \\x=2,500*4/1,000\\ \\x=10\ hours`
