Question

A hose for the hot tub at a rate of 3.61 gallons per minute. How many hours will it take to fill a 345 gallon hot tub?

Answer 1

We have a 345 gallon hot tub that fills at a rate of 3.61 gallons/min.

To calculate filling time, we need to divide as it follows:

$t=\frac{345\text{gal}}{3.61\frac{\text{gal}}{\min }}$

in that way we can find how much time does it take in minutes

$t=\frac{345}{3.61}=95.56786$

now, if we want to determine time in hours, we must divide by 60, because there are 60 min. in one hour.

$t=\frac{345}{3.61}\cdot\frac{1}{60}=1.59279$

Then, it would take approximately 1.59 hours to fill the hot tub.
