Explanation
Here average speed = total distance covered by total time taken.
= (4km + 4km) ÷ (0.16h + 0.33h)
= 8/0.49
=16.32 km/h is the average speed of the person.
Now average velocity = total displacement by total time taken.
= 0km ÷ 0.49h (the final point and initial points are same so velocity is 0)
= 0km/h.
I hope this will help you. Thank you. Please follow me or rate me.
