Given- 

  • Radius of circular path, R = 30 m
  • Time for one round = 1 minute = 60 seconds
  • Motion is uniform

Distance covered in one round = Circumference of the circle $$
2×π×R=2×3.14×30=188.4m
$$

As, $$
Speed=\frac { Distance }{Time}=\frac { 188.4}{60}=3.14m/s
$$

Therefore, the speed of the athlete is 3.14 meters per second.
