Answer:
Option C. 19 in.
Step-by-step explanation:
The wheel of a compact car has a diameter = 25 in. and the wheel of a pickup truck has 31 in. diameter.
We have to calculate the difference in the distance covered by each wheel in one revolution.
As we know distance covered by each wheel in one revolution is equal to its perimeter.
So bigger wheel will cover more distance as compared to the smaller one because bigger wheel will have more perimeter than smaller one.
Now perimeter of the wheel of a pickup truck = 2πr = 2π(31/2) = 31π in.
Perimeter of the wheel of a compact car = 2πr' = 2π(25/2) = 25π in.
Now the difference will be = 31π - 25π = 6π = 6×3.14 = 18.84 in. ≈ 19 in.
Answer will be option C. 19 in
