Question

a man covers a distance of 20 metre with 2 metre per second and 40 metre with 5 metre per second .find the average velocity of the man.​

Answer 1

Answer:

3.33m/s

Explanation:

Average velocity = total displacement/total time

Total Displacement = 20+40=60m

Time in covering 20 metre with 2m/s= 20/2=10 seconds

Time in covering 40 metre with 5m/s = 40/5=8 seconds

Total time = 10+8=18 seconds

Average velocity =60/18

=3.333m/s
