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.
C. The total distance is 105 kilometers, and the total displacement is 75 kilometers east.

Answer: B. The total distance is 105 kilometers, and the total displacement is 45 kilometers east.

60 + 45 = 105 = Distance
60 - 45 = 15 = Displacement vector magnitude. The truck ended the journey 15 km from the start ! (after traveling a distance of 105 km)
distance requires a meter stick. Displacement is a vector and also requires a compass.

d = 60 + (60-15) = 105 km.

Disp. = 60-15 = 45 km.
Answered by Henry
Correction: Disp. = 15 km.
Answered by Damon
It says it stopped 15 km from A.
