Question

A hose fills a tank at a rate of 20 gallons per minute. What is the rate in liters per hour? (1 gallon ≈≈ 3.79 liters) Enter your answer in the box. L/h

Please help!

My work: 20 gallons/ 1 minute * 1 hour/1 liters * 60minutes/1hr = 1200/1
(I seriously have no clue if this is right, or wrong, or how to get the correct answer! A step by step answer would be great, I'd really like to know how to get the right answer.)

Answer 1

For this case, the first thing we must take into account are the following conversions:

`1 gallon = 3.79 liters`

`1 hour = 60 minutes`

Then, we apply the conversions step by step.

To transform to liters per minute we have:

`(20(gal)/(min)) * (3.79(L)/(gal)) = 75.8(L)/(min)`

Then, we convert the result in liters per hour.

We have then:

`(75.8(L)/(min)) * (60)(min)/(h) = 4548(L)/(h)`

Answer:

the rate in liters per hour is:

4548

Answer 2

Hello,


`(20 \ gallons)/(1\ min) = (3.79*20\ l)/( (1)/(60)\ h)\\ =(3.79*20*60\ l)/( 1\ h ) =4548\ l/h`
