Answer: the American car gets better gas mileage.
Explanation:
American car travels 32 miles on 1 gallon of gas. This means that its gas mileage is 32 miles per gallon.
European car travels 12.7 km on 1 L of gas. We would convert 12.7 km to miles.
1 kilometer = 0.621 mile
12.7 kilometer = 12.7 × 0.621 = 7.8867 miles
We would also convert 1 L to gallons.
1 liter = 0.264 us gallons
Therefore, the gas mileage of the European car in miles per gallon would be
7.8867/0.264 = 29.87 miles per gallon.
Therefore, since 32 miles per gallon is greater than 29.87 miles per gallon, it means that the American car gets better gas mileage.
