Answer:
The total average speed is Distance/Time and the Average velocity is Change in displacement /Time
And speed is 80m/min,velocity is 40m/min
Explanation:
Radius of the circular track=200m
Distance travelled by cyclist=r+r=200m+200m=400m
Time taken by the cyclist=5min
→Average speed=Total distance/Total Time
→Speed=400m/5min
→Speed=80m/Min
→Average velocity=200m-0m/5min
→Velocity=200m/5min
→Velocity=40m/min

Answer:
Average speed= 4.19 m/s
average velocity= 0m/s
Explanation:
use formula speed=2πr/t
and in second case displacement=0
therefore velocity =0
