- Miles per gallon = (372.0 miles) / (12.0 gallons) = 31 miles per gallon
- Miles per gallon = (449.5 miles) / (14.5 gallons) = 31 miles per gallon
For Good Gas:
- Miles per gallon = (127.5 miles) / (3.75 gallons) = 34 miles per gallon
- Miles per gallon = (319.6 miles) / (9.4 gallons) = 34 miles per gallon
- Miles per gallon = (428.4 miles) / (12.6 gallons) = 34 miles per gallon
