Displacement is the shortest distance between the initial and the final position. Here, the car travels from stop A to B and returns to stop A.
Thus, the displacement of the car is 0 m/s.
let the distance travelled by the car from stop A to B = x km
The car travels from A to B and returns back to B. Thus,
total distance travelled = 2x km
Time while going from A to B = Distance travelled / Speed taken
= x/30 hours
Time while returning from stop B to A = x/50 hours
Thus, the displacement of the car is 0 m/s.
