Question

a body goes 300 metre in 10 minutes and comes back 100 metre in 5 minutes. what will be its average velocity and average speed?

Answer 1

Answer:

av. speed = total d/ total s

= 300+100/10+5

=400/15

convert min into sec

400/900

=0.44 m/s

av. velocity = total displavement / total time

= 300-100/900

200/900

=0.22 m/s
