Between 6 am to 6:30 am
Average speed = Total distance/ Time
= πr / (30 × 60 seconds)
= 4π/1800
= 0.00698 cm/s
Average velocity = Total displacement/ Time
= 2r / (30 × 60 seconds)
= 8 / 1800
= 0.0044 cm/s

Average velocity and average speed between 6 am to 6:30 pm is same as that of 6 am to 6:30 am
