Question

A bus travels 150 Miles on 15 gallons of gas. How many gallons will it need to travel 220

Answer 1

22 gallons

Explanation:

You need to do proportions. This expression means miles per gallon:

`(miles)/(gallons)`

The equation will look like:

`(150)/(15) =(220)/(x)`

Then, you cross multiply.

150x = (220)(15)

150x = 3300

Then, divide.

`(3300)/(150) = 22`

Answer 2

22

Explanation:

220 x 15 ÷ 150 = 22

or each gallon gives him 10 miles.

for 220 miles he needs 22 gallons
