disp.=0. as she again reached the same point from where she started and then avg. velocity is also zero.
and avg. speed will be = total distance÷ total time taken

Answered by harsh3374chauhan

displacement is zero
avg velocity is also zero Bcz velocity is displacement / time
avg speed = distance/time
so = 2πr/time
= 2*3.14*0.5/1 =3.14 km/h

meenakshi997sa: hey... its 2πr/time ... u forgot to place the value of radius in last step... answer will be 3.14km/hr

wendyyy: oh... thanks:)

meenakshi997sa: ☺☺

Anonymous: yes i left it for u to solve,as i stated the formula and now anyone can solve it

harsh3374chauhan: sry by mistake
