Question

A car traveled 63 miles on 3 gallons of gas. what proportion can you set up to determine how many miles ,m, the car can travel on 7 gallons of gas.

Answer 1

For one gallon the car will travel (63/3) miles
therefore for 7 gallons the car will travel
(63/3)*7 = m

Answer 2

The car can travel 147 miles on 7 gallons of gas

Explanation:

A car traveled on 3 gallons of gas = 63 miles

car traveled on 1 gallons of gas =
`(63)/(3)` = 21 miles

Therefore, car traveled on 7 gallons of gas = 21 × 7 = 147 miles.

The proportion will be =
`\frac{\text{Total traveled distance}}{\text{required gallons of gas}}` × 7 =
`(63)/(3)` × 7

The car can travel 147 miles on 7 gallons of gas.
