To find the unit rate of miles per gallon, divide the total number of miles driven (325 1/2 miles) by the total number of gallons of gas used (15 1/2 gallons).
325 1/2 miles divided by 15 1/2 gallons equals 21 miles per gallon.
Therefore, Sierra's unit rate of miles per gallon is 21 miles per gallon.
