If a person is walking at 2 meters per second, that means that for every 1 second she is walking, she moves a distance of 2 meters.

So, let's say that she is indeed walking at 2 meters per second.
How far does she walk in 2 seconds?
How far does she walk in 3 seconds?

You should have gotten answers of 4 meters, then 6 meters.



Try filling in the values for distance in the chart below.   Check with your group members to make sure that everyone agrees with the answers.

What if you were given two pieces of information:   A person walks 12 meters in 4 seconds.    You should those two values side by side on the chart above.   The answer, since it is on the chart, is of course 3 meters per second  (or m/s for short).

What is the mathematical operation required to take 12 meters, 4 seconds, and yield 3 meters per second?

Does that same operation work with all rows?    Give an example, and show your teacher.


Finally... does this give you some idea how to measure the speed of a walking person?
