Question

Gas mileage is the number of miles you can drive on a gallon of gasoline. A test of a new car results in 430 miles on 10 gallons of gas. How far could you drive on 55 gallons of gas? What is the car's gas mileage?

Answer 1

With 55 gallons of gass the car is able to travel 2,365 miles. Its mileage is 43 miles per gallon.

Explanation:

Since the car ran 430 miles on 10 gallons of gas, we can calculate its mileage by dividing the distance traveled by the amount of gas used, so:

`mileage = (430)/(10) = 43 \text{ } \frac{\text{miles}}{\text{gallon}}`

If he had 55 gallons of gas on the tank, then he'll be able to travel:

`distance = gas*mileage\\distance = 55*43 = 2,365 \text{ miles}`

With 55 gallons of gass the car is able to travel 2,365 miles. Its mileage is 43 miles per gallon.
