Question

a practical move from point A to B travelling some distance with speed 60 km per hour then it moves from B to a with speed 40 kilometre per hour find displacement distance travelled average velocity and average speed for the entire journey ​

Answer 1

Answer:

The displacement is 100 km, the average speed is 50 km/hr and the average Velocity is also 50 km/hr.

Explanation:

Let speed from point a be V1

and speed from point b be V2

Average speed = V1 + V2 / 2

= 60 + 40 / 2

= 100 / 2 = 50 (ans).

displacement distance=60+40=100(ans).

Since, trains move in a straight line

Hence, Average velocity = Average speed = 50 km/hr (ans).
