For this experiment, you will need a stopwatch and a piece of paper to mark your time.
In this experiment, the distance from one end of the walkway to the other is 279 feet and 10 1/2 inches.
I clocked the walkway at 2 minutes and 17.78 seconds from one end to the other.
The following is a table showing the different times each student received, the calculation, and the difference.
2 min 17.78 sec..........137.78 sec......... -
2 min 18.70 sec..........138.70 sec......... +
2 min 18.40 sec..........138.40 sec......... +
2 min 18.29 sec..........138.29 sec......... +
2 min 18.15 sec..........138.15 sec......... -
2 min 18.71 sec..........138.71 sec......... +
2 min 17.44 sec..........137.44 sec......... -
2 min 18.11 sec..........138.11 sec......... -
2 min 18.34 sec..........138.34 sec......... +
2 min 17.99 sec..........137.99 sec......... -
2 min 18.15 sec..........138.15 sec......... -
Now the next step is to add the second column, calculation, and divide by 11, to get the AVERAGE. The average is 138.19
To get the 3rd column, simply take the difference between the average and the calculation. If the average is less than the calculation, then it is "+", and if the average is more than the calculation, then it is "-".
