Answer:
53.8 mpg is the mileage.
Step-by-step explanation:
The normal gasoline mileage of a car is 48 mpg.
On a smooth road car's mileage is 12% higher. Then we have to calculate the mileage of car on smooth road.
By the statement of the question mileage of the car on smooth road = Normal gasoline mileage + 12% of normal gasoline mileage
= 48 + 12% of 48
= [tex]48+(\frac{12}{100})(48)[/tex]
= 48 + 12×0.48
= 48 + 5.76
= 53.76
≈ 53.8 mpg
Answer is mileage of car on smooth road will be 53.8 mpg
