Average velocity is the displacement of an object over time. To find the average speed of an object we divide the distance travelled by the time elapsed. We know that velocity is a vector quantity and average velocity can be found by dividing displacement by time.

Answer:
Arranging the given values in the ascending order, we have 14, 15, 19, 21, 24, 26, 32, 33.
As the given number of observations is even (n=8), then the average of the two middle terms is the median, i.e., (n2)the and (n2+1)the observations average.
i.e., median is the average of the 4th and the 5th terms.
∴ Median =21+242=22.5
