Question

Your car gets 19.7 miles per gallon (mpg) on a trip of 547 miles. How many gallons of gasoline did you use on the trip?

Answer 1

Approximately 27 or 28 gallons of gasoline.

Explanation:

`19.7` miles per gallon means for every `19.7` miles travelled, your car uses `1` gallon of gasoline. So calculating the number of gallons used during a `547` mile trip is done by division.

`547/19.7` `=` `27.7664974619`

`27.7664974619` is nearly `28` gallons.
