Michelle family drove 272.48 miles.
=> Michelle calculated that they drove 26.2 miles per gallon of gas.
Question: how many gallons of gas did the car use?
=> Unit rate = 26.2 miles per gallon
Now, they travelled a total of 272.48 miles.
To get the answer let’s divide the total miles they travel to the number of miles for each gallon of gas.
=> 272.48 / 26.2 = 10.2
Thus, they need 10.2 gallon of gas to get to their destination.
