## How fast do you walk or march?

Let's try an experiment to see if we walk two, three or four miles per hour?

Since we are pretending to be in a parade we could try to toss a ball back and forth 16 inches high by 16 inches wide as we walk.

The distance from here to there is 100 feet and we will time how long it takes you to walk this distance while you toss the ball.

Use the clock on the wall or we will time you with this stopwatch.

If you drop the ball often you may wish to repeat this experiment and take an average or exclude data that does not fit your normal walking time.

Represent rate of walking in three or four ways: feet per second, inches per second, miles per hour, and maybe meters per second.

If you count your steps you will be able to determine your stride length and stride frequency.

For time changes note that there are 60 seconds in a minute and 60 minutes in an hour.

For units of distance note that twelve inches equals one foot and 5280 feet equals one mile. Also 2.54 centimeters equals one inch.

Most of us are in this picture but not in order of names.
