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

Answer:

1.73 hours

Step-by-step explanation:

This can be solved with proportions.

$\frac{2.58 gallons}{1 minute} = \frac{268 gallons}{x minutes}$

Cross multiply and you get:

$2.58x gallons * minutes = 268 gallons * minutes$

Divide by 2.58 gallons and you get:

$x minutes = \frac{268 gallons}{2.58 gallons} * minutes \\x minutes = 103.876 minutes\\x = 103.876 minutes$

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