Divide the miles by the gallons used.
315.5/11.4 = 27.6754386

15 mpg (miles per gallon). The key to this 'word problem' is understanding that "miles to the gallon" or more commonly, 'miles per gallon', means DIVISION. So, 300 miles per 20 gallons means: (300 miles) / (20 gallons) = 15 miles per gallon.
20.9 miles per gallon 389 / 18.6 = 20.9140
20mi = 1gal 555mi x (1gal/20mi) = 27.27gal
Take the total miles, 21,000, and divide by 21 miles per gallon to get the answer of 1000 miles.

The number of miles driven divided by the amount of gallons to drive that distance. If you drove 330 miles and it took 10 gallons to refill the tank, then you got 33 miles per gallon. You are only able to compute this if you start with a full tank and then refill the tank back to full after you drove a certain distance or start with a specific amount of gas and drive till you run out of gas.
He needs to know how many gallons the tank holds. Then the can divide the amount of miles by the amount of gallons, to find out how many miles per gallon he gets.
