Can you measure the average speed and average velocity ?

Explanation

1) Select two positions (say A and B) 50 meters apart in the ground.
2) Ask some students to stand at point A.
3) Ask another group of students with stop watches to stand at B.
4) When you clap your hand, the students at A start running towards the point B in any direction or path.
5) At the same time the students at B start their stop watches.
6) Observe that for each runner there is a student at B to measure the time taken for completing the race.
7) Note the time taken by each student to cover the distance between the points A and B in the table given below.

8) The student who took the least time to reach B (from A) is said to be the fastest runner.
9) The student who is fastest runner has the greatest average speed.
10) Thus we measure the average speed of any moving body.
