Question

A hose fills a hot tub at a rate of 4.42 gallons per minute. How many hours will it take to fill a 294-gallon hot tub?

Answer 1

1 hour and 7 minutes

Explanation:

1. set up two equations:
   `(4.42g)/(1min)` =
   `(294)/( ? min)`
2. cross multiply: 4.42x =294
3. solve for x: 294 ÷ 4.42 = 66.52 or 67 minutes

The question is asking for hours rather than minutes so...

- 1 hour is 60 minutes

67 min - 60 min = 7 min

Therefore, it would take 1 hour and 7 minutes to fill a 294-gallon hot tub.

Answer 2

Answer:21hours

Explanation:

Per minute a hose fills hot at 4.42

Take note 60secs =1 min

60min=1h

Therefore

294×4.42/60

=21hours
