The length of the walkway was 279 feet and 10.5 inches. The only equipment necessary for this experiment was a stopwatch. We rode the walkway in pairs. The time started when we stepped on the walkway, and ended when we stepped off.
You would think that everyone would have the same times, since all we did was ride the walkway. The times did all vary, however, except for two.
There are some things that could have changed the outcome of this experiment. For example, people with longer strides may step farther onto the walkway. This would make their time shorter. Also, having to move out of other traveler's way would affect your time.
The other part of this experiment involved creating a data sheet. The data sheet consisted of the mean average, the middle score, and the mode. The mean average is the sum of all scores divided by the total number of scores. The middle score involves arranging the scores in ascending order (smallest to largest), taking the two middle scores, and averaging them. The mode is a score that occurs more than once.
We again used the d=rt formula to
find out our rate.
