Answer: The mileage rating of the car is 30.05 miles per gallon
Step-by-step explanation:
We are given:
Mileage rating = 12.8 km/L
To convert this level into milligrams per deciliters, we use the conversion factor:
1 mile = 1.61 km
1 gallon = 3.78 L
Converting the above rating into miles per gallon, we get:

Hence, the mileage rating of the car is 30.05 miles per gallon
