Answer:
Displacement, d = 0
Step-by-step explanation:
It is given that,
Distance traveled by NASCAR racers, d = 500 miles
They finish exactly where they started. The only difference between the distance and displacement is the distance is the overall path covered and the displacement is the shortest path covered.
Here, the initial and final position of the racers is same i.e. 500 miles. So, their displacement is :
d = final position - initial position
d = 500 - 500
d = 0
So, their displacement is 0 miles. Hence, the correct option is (A).
