Velocity = displacement/ time.
Here, Displacement= 0 m (as the athlete goes round a circular track)
time = 10 s
Hence, velocity = 0 m/10s
= 0 m/s.
Here, Displacement= 0 m (as the athlete goes round a circular track)
time = 10 s
Hence, velocity = 0 m/10s
= 0 m/s.

Thank you soo much ♥★←
you are welcome :)
I didn't get!!!!!!!
Circumference = 2 π r
= 2 X 22/7 X 7
= 44 m
hence. speed = distance/time
= 44m/10s
= 4.4 m/s.
= 2 X 22/7 X 7
= 44 m
hence. speed = distance/time
= 44m/10s
= 4.4 m/s.

speed = distance / time
distance = circumference of circle = 2πr = 2 * 22/7 * 7 = 44m
= 44/10 m/s
velocity = displacement / time
As the athlete moves in a circular path displacement is zero
= 0/10 = 0 m/s
distance = circumference of circle = 2πr = 2 * 22/7 * 7 = 44m
= 44/10 m/s
velocity = displacement / time
As the athlete moves in a circular path displacement is zero
= 0/10 = 0 m/s
