Answer:
Sara drives 22.5 miles per gallon and 299.25 miles in 13.3 gallons of gas.
Step-by-step explanation:
Sara drives 72 miles on 3.2 gallons of gas and we have to calculate how many miles per gallon she can drive.
By unitary method
∵ 3.2 gallons of gas is used to drive = 72 miles
∴ 1 gallon of gas is used to drive = 72÷3.2 miles
= 22.5 miles
∴ 13.3 gallons of gas is used to drive = 13.3×22.5 = 299.25 miles
Therefore Sara drives 22.5 miles per gallon of gas and on 13.3 gallons of gas she drives 299.25 miles.
