Hi there !!
Radius = r = 105 m
Time = t = 2 min = 120 sec
Distance traveled = circumference of the circle = 2πr = 2 × 22/7 × 105 = 660 m
speed = distance / time
= 660/ 120
= 5.5 m/s
Radius = r = 105 m
Time = t = 2 min = 120 sec
Distance traveled = circumference of the circle = 2πr = 2 × 22/7 × 105 = 660 m
speed = distance / time
= 660/ 120
= 5.5 m/s
