one complete round= 2πr
2×22/7×105 =44×15=660m
speed =distance/time
=660/120 m/sec
2×22/7×105 =44×15=660m
speed =distance/time
=660/120 m/sec

Given
t=2 min = 2 * 60s = 120s
Radius =105m
So, distance or circumference of the circular track = 2πr = 2 * 22/7 * 105= 660m
Therefore, speed = distance/time
=660/120 m/s
= 5.5m/s
Ans: Speed of the cyclist is 5.5m/s
t=2 min = 2 * 60s = 120s
Radius =105m
So, distance or circumference of the circular track = 2πr = 2 * 22/7 * 105= 660m
Therefore, speed = distance/time
=660/120 m/s
= 5.5m/s
Ans: Speed of the cyclist is 5.5m/s
