ANSWER:
Distance = 25π metre
Displacement = 0

EXPLANATION:
The time taken by the athlete to complete 1 round = 30s

So if he runs for 30s then he will complete 1 round and will be at the starting point

Therefore the distance will be the circumference of the circle (ie 25π metre)
and the displacement will be 0.
0
