radius =110cm
time =2 min or 120sec
speed=(2 pie r)/t
speed =(2×3.14×110)/120
speed = 5.756m/sec
time =2 min or 120sec
speed=(2 pie r)/t
speed =(2×3.14×110)/120
speed = 5.756m/sec

but where he changed 110cm in to m
oh ya
Sorry my mistake

radius = 110
Circumference = 2πr
Here,
Circumference = 2(22/7) × 110
Circumference = 691.43 cm [approx]
××××××××××××××××××××××××
Time = 2 minutes = 120 seconds
Speed = distance/time
Here,
Speed = 691.43/120 => 5.77 cm/sec
I hope this will help you
