A hose fills a hot tub at a rate of 3.45 gallons per minute. How many hours will it take to fill a 280 -gallon hot tub?

Formula will be

Q = V / t

Where,

Q-flow

V - volume

t - time

So time =

t = V / Q

Substitute the values

t = (280) / (3.45)

t = 81.16 minutes

Convert to hours:

t = (81.16) * (1/60)

t = 1.35 hours

It will take t = 1.35 hours

For this case we must use the following definition:

Q = V / t

Where,

Q: flow

V: volume

t: time

Clearing the time we have:

t = V / Q

Substituting the values:

t = (280) / (3.45)

t = 81.16 minutes

In hours we have:

t = (81.16) * (1/60)

t = 1.35 hours

Answer:

it will take to fill to 280 - gallon hot tub а bout:

t = 1.35 hours
