Time = 2 min=180 seconds
Total distance traveled= 2r= 240
Average speed = total distance/total time
Avg speed= 240/180
Avg speed = 3m/s
Total distance traveled= 2r= 240
Average speed = total distance/total time
Avg speed= 240/180
Avg speed = 3m/s

Average speed = Total distance / Time
= Half Circumference / Time
= πR / T
= (π × 120 m) / (2 × 60 seconds)
= π m/s
= 3.141 m/s
[Note: I took radius in meters even though it’s not mentioned in the question]
