Answer 1

car travels from stop A to B with a speed of 30km/h and returns back to A with a speed of 50km/hr. Find displacement and distance travelled by the car. what is the average speed of the car

Answer 2

Explanation:

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 hoursl
