Question

os a car travels from stop A to stop B with
la speed of 30km/h and then returns back to
A with speed of sokm/h. Find
i) Displacement of the can
ii) Distance travelled by the car
average speed of a car

Answer 1

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
