Question

A hose fills a hot tub at a rate of 2.58 gallons per minute. How many hours will it take to fill a 268​-gallon hot​ tub?

Answer 1

1.73 hours

Explanation:

This can be solved with proportions.

`(2.58 gallons)/(1 minute) = (268 gallons)/(x minutes) \\`

Cross multiply and you get:

`2.58x gallons * minutes = 268 gallons * minutes\\`

Divide by 2.58 gallons and you get:

`x minutes = (268 gallons)/(2.58 gallons) * minutes \\x minutes = 103.876 minutes\\x = 103.876 minutes\\`

And to find out the number of hours that is, divide by 60 and you get 1.73 hours.
