Question

A car gets 24 miles per gallon of gasoline. How many gallons of gasoline would the car need to travel 144 miles?

Answer 1

So 1 gallon = 24 miles, how many gallons to 48 miles?

If you can figure that out, how many gallons to 72 miles? (then just keep going)

Answer 2

Ok thank you!

Answer 3

6 gallons of gasoline you divide 144 by 24 then to check your answer multiply your answer by 24

Answer 4

Think about it this way.\[\text{gallons}=\text{miles}\cdot \frac{\text{gallons}}{\text{miles}}=\boxed{\dfrac{\text{miles}}{\left(\dfrac{\text{miles}}{\text{gallons}}\right)}}\]So just plug in how many miles per gallon the vehicle requires and then how many miles you've gone.

Answer 5

Couldn't you divide 144 by 24 and get 6 gallons?

Answer 6

Yep that's exactly the equation I wrote above.
