:?: miles per gallon
odometer reads 38,451.4
odometer reads 38,687.0 at fillup gets 12.6 gallons How many miles to the gallondoes person get?
Do you subtract the odometer readings and divide by 12.6 gallons????????

\(\displaystyle \L\;\frac{Miles}{Gallons}\;=\;\frac{StopMiles\;-\;StartMiles}{Gallons}\)

It looks to me like you have the right idea.
