hiii!!!
here's ur answer...
given the radius of the circular track = 21m
circumference of the circular track = 2πr
= 2 × 22/7 × 21
= 44 × 3
= 132m
therefore total distance covered by the cyclist = 132 × 5
= 660m = 0.66km
total time taken = 12h
average speed = distance/time
= 0.66/12
= 0.055km/h
hope this helps..!!
