How fast do you normally walk? Using a meter stick or a string of known length, lay out a straight course of 40 or 50 meters. Then use a watch with a second hand or a stopwatch to determine:
a. Your normal walking speed in m/s.
b. Your walking speed for a brisk walk.
c. Your jogging speed for this same distance.
d. Your sprinting speed for this distance. Record and compare the results for these different cases. Is your sprinting speed more than twice your speed for a brisk walk?
