Given: A 3-column table with 5 rows. The first column has entries empty, distance travelled (meters), time (initial) (seconds), time (final) (seconds), elapsed time (seconds), average speed (meters per second). The second column labeled Trial A has entries 4.0, 2.0, 2.5, 1.5, 2.7. The second column labeled Trial B has entries 4.0, 1.5, 4.5, empty, empty. Use the data table on the left to complete the calculations.
To find:
(1) The elapsed time for Trial B.
(2) The average speed for Trial B.
Solution:
(1)
In order to check the time elapsed for Trial B, the fourth row and the third column must be checked. The fourth row has elapsed time for both the trials and the third column has information about Trial B. Now, according to the question, the elapsed time for Trial B is empty.
(2)
In order to check the average speed for Trial B, the fifth row and the third column must be checked. The fifth row has the average speed for both the trials and the third column has information about Trial B. Now, according to the question, the average speed for Trial B is empty.
Therefore,
(1) The elapsed time for Trial B is empty.
(2) The average speed for Trial B is empty.
