Answer:

Here,

Radius = 40m

circumference= π×40^(2)

= 5026.5m

So,

distance travelled = 5026.5m

Time taken = 5min/ 300sec

Average speed = Distance/ time

= 5026.5/ 300

= 16.75m/sec

After completing one revolution the total displacement of the child is zero

Hence,

Averege velocity = Displacement/ time

= 0/300sec

= 0
