5. A car travels from stop A to stop B with a speed of 30 km/h and then returns back to A with a speed of 50 km/h. Find (i) displacement of the car. (ii) distance travelled by the car. (iii) average speed of the car. A car travels from stop A to stop
Please give explanation too.

Answer:
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
