Ans1= distance = he took four rounds and track is 200m so 4*200 =800m
ans2=0 because he comes back to his initial position 
ans3=no the motion is not uniform because the athletes tired and his speed will increase and decrease
ans4 no it is not equal because distance is actual path covered by the body whereas displacement is shortest path between initial and final position  and the athlete come back to his own place so the displacement is 0
0
