### OMG! MPG

In a time when everyone is concerned about the environment, we hear a lot about how many miles per gallon a car can get. Fuel economy is the average mileage a car travels per gallon of gasoline. The corporate average fuel economy requirement, CAFE, is currently 27.5 mpg. The federal government is raising CAFE to 34.1 mpg by 2016, but is also considering raising CAFÉ between 47 and 62 mpg by 2025. While cars will be more expensive, car owners will save money on fuel in the long run. Let's say your family is taking a road trip that is 1,278.5 miles long. How many fewer gallons of gas would you need for a car that gets 62 mpg than a car that gets 27.5 mpg?

You would need about 26 fewer gallons of gas.
