Acar goes from point a to point b, five miles away and then returns to point a. the car is going 15 mph. what is the velocity of the car?   a. –30 mph   b. 0 mph   c. +15 mph   d. +45 mph

B) 0 mph

Explanation:

Velocity is a vector quantity. It can be measured as rate of change of displacement.

Displacement is the straight path length between final and initial position of the body in motion.

It is given that the car goes from point A to point B and the returns to Point A. Hence, the net displacement of the car is 0 as the car comes back to its initial position.

Therefore, the velocity of the car is 0 mph.

Option B is correct.
