The velocity of an object is the displacement in a unit interval of time.

In the problem, we assume that the track is a straight one and 2000 m in length. Here the winner takes 40 seconds to cover a distance of 2000 m.

So the velocity is given by (2000/ 40) m/s

=> 50 m/s

Therefore the required velocity of the winner is 50 m/s.
