Answer:
9.09m/s
Explanation:
now velocity of a body is measure of the distance covered by a body in a particular time frame,so simply its the rate at which distance is covered,
thus mathematically V(velocity)=d(distance covered)/t(time it takes to cover the distance)
hence V=100m/11s
which is V=9.09m/s.
so this means the runner covers 9.09m in every second , well not bad lol !
