Question

If Susie's car traveled 372 miles on 12 gallons of fuel, then her car gets about howmany miles per gallon?

Answer 1

We will investigate how to determine the mileage of any vehicle given the amount of distance travelled while burning a volume of fuel.

Susie's car teavells:

$\text{Distance travelled ( d ) = 372 miles}$

Susie's car cinsumes:

$\text{Fuel consumption ( c ) = 12 gallons}$

Mileage is a car performance parameter that defines the fuel economy. It is usually expressed as a ratio of distance travelled to the amount of fuel consumed as follows:

$\text{Mileage = }\frac{Dis\tan ce\text{ Travelled ( d )}}{Fuel\text{ consumed ( c )}}$

We will plug in the respective quantities in the above ratio as follows:

$\text{Mileage = }\frac{372\text{ miles}}{12\text{ gallons}}$

Simplfy:

$\text{\textcolor{#FF7968}{Mileage = 31 }}\textcolor{#FF7968}{\frac{\text{ miles}}{\text{ gallon}}}$

Hence, Susie's car will travel 31 miles for each gallon of fuel consumed!
