Question

Dan drove 246 miles using 9 gallons of gas. At this rate how many gallons of gas would he need to drive 410 miles ?

Answer 1

He will need to use 15 gallons of gas.

To solve this problem, we can write and solve a proportion.

It would be:

246 / 9 = 410 / x

If you cross multiply and divide, you will get that x = 15.
