Problem Statement:

If a car has a fuel economy of 23 miles per gallon (mpg) and has a gas tank that holds 14.5 gallons of fuel, what is its range? It if travels at an average speed of 50 miles, what is its endurance?

Solution:

Range:

Endurance:

In reality, you wouldn't want to run the tank dry, so the practical range and endurance are smaller than these values.
