A truck moves 60 kilometers east from point A to point B. At point B, it turns back west and stops 15 kilometers away from point A. What are
the total distance and total displacement of the truck?
A. The total distance is 105 kilometers, and the total displacement is 15 kilometers east.
B. The total distance is 105 kilometers, and the total displacement is 45 kilometers east.
C. The total distance is 60 kilometers, and the total displacement is 60 kilometers east.
D. The total distance is 60 kilometers, and the total displacement is 45 kilometers east
E. The total distance is 105 kilometers, and the total displacement is 75 kilometers east.

The total distance is 105 kilometers, and the total displacement is 15 kilometers east.

Explanation:

A truck moves 60 km east and then 45 km (60 - 15) back to west. The total distance will be,

Distance = 60 + 45 = 105

Distance is a scalar quantity that refers to the total space covered by a truck (object).

Displacement is a vector whose length is the shortest distance from the initial to the final position of a point undergoing motion.

The truck moves from Point A to Point B, covers 60 km. Then the truck turns back from point B to point C, 15 km away from the point A. So the displacement will be

Displacement = 60 - 45 = 15

Displacement is the difference between point A and C.
