Verified Answer :

Ok so 2.5 times 60 to get qt/hr then divide 150 by 4 to get gal/hr. You should get 37.5gal/hr

Answer:

Correct option is:

b. 37.5

Step-by-step explanation:

We know that 1 qt=0.25 gal

also 1 min=0.0166 h

2.5 qt/min = \(2.5\times \dfrac{1\ qt}{1\ min}\)

                 = \(2.5\times \dfrac{0.25\ gal}{0.0166\ h}\)

                 =\(37.5\times \dfrac{1\ gal}{1\ h}\)

                 = 37.5 gal/h

Hence, Correct option is:

b. 37.5
