Question

If a car can drive 62 miles on 3 gallons of gas, how many gallons of gas will it use to travel 231 miles?

Answer 1

11 gallons of gas is needed to travel 231 miles.

Explanation:

We can set up a proportion for this problem.

For every 62 miles, you use 3 gallons of gas.

`(62)/(3)*(231)/(?)`

Now, let's cross multiply.

`(693)/(62)` ≈
`11`

So, you will need about 11 gallons of gas to travel 231 miles.
