Distance covered in one round = circumference of the circular track
= πd (where d is the diameter)
= π x 200m
= 628.32m (approx.)

Therefore, the athlete covered a distance of 628.32m in 40s.

As the diameter is 200 
so the radius will be=1/2 of 200m
                               = 100m
now , distance =2*22/7*100
                        =200*22/7
                        =628.57143m
