Question

a man starts from his home at 8 a.m. to his office he walks with a speed of 2 metre second inverse -1 on a road up to his office 3 kilometre away from his home he stays in the office upto 4 p.m. and returns to his home by bus which moves with a speed of 10 metre second inverse -1 calculate the time taken by a man to reach his office and time taken by the man to reach his home also plot (x minus t )graph of hismotion​

Answer 1

While going; v=2m/s  ,  s=3km=3000m  

Therefore, t=s/v

                   =3000m/(2m/s)= 1500s

While returning; v=10m/s  ,  s=3km=3000m

Therefore, t=s/v

                   =3000m/(10m/s) = 300s

Sorry, their is a problem in attaching the v-t graph
