Question

Q – 8. A cyclist performs motion with constant speed on a circular path of riding 66 m. If he takes 132 s to

complete one round, calculate his average speed

Answer 1

average speed =total distance ÷total time
66÷132
1÷2=0.5
it is his average speed
HOPE IT HELPS YOU

Answer 2

Explanation:

Here, radius(r)=66m

Time is taken to complete one round (t)=132s

∴Av.speed=

Total time taken

Total distance travelled

or, Av.speed=

132

2πr

m/s

or, Av.speed=

132

2π×66

=3.14m/s
