Question

a body travels from A to B at 40 metres per second and B to A 60 metre per second calculate its average speed an average velocity ​

Answer 1

Answer:

Explanation: u=initial speed or velocity ,  v=final speed or velocity

                      u=40m/s                                v=60m/s

Average speed=(v+u)/2

                         =(60+40)/2

                         =100/2

Average speed =50m/s
