Cyclist moving in circular path so it's displacement is 0
Now the speed of cyclist is = total distance /time
,radius of path =42/2
Total distance =2×22/7 ×42/2
Total distance =132 ×3 =396
Time =60sec
speed = total distance /time
Speed = 396/60 =6.6m/sec

Answer:
Explanation:
Radius = Diameter/2
Radius = 21 m
3 rounds = 3 times the circumference
= 3 * 2 * pi * 21 * 21
= 6.6
