Question

a hose fills a hot tub at a rate of 2.38 gallons per minute. how many hours will it take to fill ac 350 gallon hot tub

Answer 1

Answer: 2 hours 27 minutes

Explanation:

If 1 hose filled 2.38 gallons in 1 minute.

Then, 350 gallon will be filled in Z minutes

Now cross multiply

2.38 gallons = 1 minute

350 gallons = Z minute

2.38 x Z = 350 x 1

2.38Z = 350

Divide both sides by 2.38 to obtain value of Z

2.38Z / 2.38 = 350 / 2.38

Z = 147 minites

Since, answer must be provided in hours, convert 147 minutes to hours

60 minutes = 1 Hour

Then 147 minites = 120 + 27 minutes

So, 147 minutes = 2 hours and 27 minutes

Thus, it will take 2 hours 27 minutes for the hose to fill the 350 gallon.
