Taylor wanted to determine the gas mileage she was getting on her car. She filled the gas tank on her car when the odometer read 38,948 miles. After 7 days the odeometer read 39,333 miles and it took 11 gallons of gas to fill the tank. How many miles to the gallon did Taylor's car achieve?

She drove a total of 39,333 – 38,948 = 385 miles

Assuming the tank was emptied on the 7th day, it took 11 gallons of gas to drive 385 miles.

She can drive at a rate of 385 miles per 11 gallons of gas.

\(\frac{385\,\text{miles}}{11\,\text{gallons}}\,=\,\frac{385\,\text{miles}\,\div11}{11\,\text{gallons}\,\div11}\,=\,\frac{35\,\text{miles}}{1\,\text{gallons}}\)

That is, 35 miles per gallon
