Answer:
The car travel 2.52 m
Explanation:
This problem gives us the time and speed of the car with the echolocation system, and they ask us for the distance traveled, we can use the report motion equation.
Let's start by calculating the relative speed of the two cars, which in this case is the initial mass because the second vehicle is at rest.
v = d / t
d = v t
d = 14 0.18
d = 2.52 m
The car travel 2.52m
I'm not 100 percent sure but I think the correct answer is B. Disconformity.
