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?

Sagot :

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:

[tex]t=\frac{345\text{gal}}{3.61\frac{\text{gal}}{\min }}[/tex]

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

[tex]t=\frac{345}{3.61}=95.56786[/tex]

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

[tex]t=\frac{345}{3.61}\cdot\frac{1}{60}=1.59279[/tex]

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