Answer:
The runner's Average Speed is 16 km/h and average Velocity is 0
Step-by-step explanation:
Avg Speed= Total Distance/ Total Time
Avg Speed = 2(Length of Circuit)/ 5/4 hrs
Avg Speed= 20/ 5/4
Avg Speed= 20 * 4/5
Avg Speed= 16 km/h
Avg Velocity= Total Displacement/ Total Time
Avg Velocity= 0/ 5/4 hrs
Avg Velocity= 0
