19. To get Average time:
20. 5.69+5.65+5.47= 16.81
21. 16.81/ 3 = 5.6033 seconds
22. Do that with all 5 heights and 3 trials.
23. 16.81 represents every number added up for every trial
24. 3 is the number of trials.

26. To get Velocity Average:
27. 2.09/ 5.6033 = 0.373 m/s
28. V=D/T
29. Do that with all 5 heights and 3 trials
30. 2.09 represents the height of the board.
31. 5.6033 represents the average time of each trial.
