Answer: Conrad's car gets 16 miles per gallon more than Mr and Mrs Finks car.
Step-by-step explanation:
Miles per gallon = total miles driven/number of gallons of fuel used
Mr. And Mrs. Fink drove 462 miles on 21 gallons of fuel. It means that the number of miles that they drove per gallon of fuel is
462/21 = 22 miles per gallon
Conrad drove 456 miles on 12 gallons of fuel. It means that the number of miles that Conrad drove per gallon of fuel is
456/12 = 38 miles per gallon
The difference in the number of miles per gallon that they drove is
38 - 22 = 16 miles per gallon
