Question

Car A used 40.5 L of gasoline to travel 450 km. Car B used 18.7 L to travel 220 km. Circle the car with better fuel mileage. Justify your answer by calculating each car’s L/100 km rate. Show your work.

Answer 1

Car B has the better fuel economy.

Explanation:

Calculate the fuel consumption for the two cars:

Car A: (450 km) / (40.5 L) = 1.11 km per L

Car B: (220 km) / (18.7 L) = 1.18 km per L

Car B goes further on one L of gasoline than Car A.
