In this video, Mahalo math expert Julie Clark shows you how to calculate your gas mileage.
Step 1: Start with a Full Tank
- Take your car to a gas station and fill up your tank. Write down the exact mileage found on your odometer reading.
- Drive around like you normally would until your car needs refueling.
- Fill up your tank again, and this time, record how many gallons it takes. You can find this number on the gas pump.http://www.fueleconomy.gov/mpg/MPG.do?action=calcMPG
Step 2: Calculate Your Gas Mileage
- Check your odometer reading again and write down the new number
- Subtract the first odometer reading from the second one. This will tell you how many miles you've driven.
- Divide this number by the number of gallons it took to fill your car. The resulting number is your car's current miles per gallon.http://www.fueleconomy.gov/mpg/MPG.do?action=calcMPG
- 300 miles driven/15 gallons of gas=20 miles per gallon
