Answer:

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

Step-by-step 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.

For further understanding, see the attached picture.
