HEY!
_______________
a) Time taken to complete 1 rounds = 20 s
1 minute 10 seconds = 70 seconds
Number of rounds that can be completed in 70 seconds = 70/20 = 3.5 rounds
Distance travelled = circumference of circle = 2 pie r
Diameter= 200
Radius= 100
Distance travelled = 2 *3.14*100*3.5 = 2198
Displacement = Shortest distance travelled
3 rounds = Displacement = 0 , as initial and final point is same.
Now, 0.5 = half round = diameter of ground = 200 m
Thus, displacement = 200 m.

0 because displacement will be zero as the athlete returned to its initial position.
So,
0/20 sec = 0
