Answer:
Average speed will be 1.5 m/s and average velocity will be zero
Explanation:
Average speed=Total distance covered / Total time taken =180+180/ 2+2=90 metre/min=90/60=1.5 m/s
Average velocity = Total displacement /Total time taken =0m/s
Since net displacement = 0(intial and final point are same)

Answer:
Average velocity = 0
Average speed = 90m/min
Explanation:
total distance traveled = 360m
time taken = 4min
a speed = 360/4=90m/min
displacement = 0
time= 4min
a velocity = 0/4=0
