Question

a body travels from station A to B at 40 metre per second and from station B to A at 60 metre per second. What is the average velocity of the body ?
​

Answer 1

Answer:

Hope u like my process

=====================

=>Let the distance from a to b be x m

=> Total distance travelled = 2x m

=> Speed from a to b = 40 m/s

=> time taken while travelling from a to b

=> speed from b to a = 60 m/s

=> time taken while travelling from b to a

=> Total time taken

=> Average speed

______________________

=> Total displacement = x - x =0 m

=> Average velocity

Answer 2

Answer:

average speed is 50 m\s

40+60/2
