Show that avertage velocity of the object over an interval of time is either smaller than or equal to the average speed of the object over the same interval.

Explanation

Since, avetage velocity=(displacement )/(total time taken)
and average speed =(total distance travelle)/(total time taken)
Since, displacement of an object can be equal to or less than the total distance travelled in a given time, hence, average velocity of an ohject over an interval of time is either equal to or samller than the average speed of the object over the same interval in time.
