Answer:

Row 2 = 4.07

Row 3 = 6.03

Explanation:

The prompt gives you the correct equation for calculating the average. For this question, it may make more sense to write the equation as follows:

Average Time = (Time Trial 1 + Time Trial 2 + Time Trial 3) / # of Trials

So, for a distance of 20 cm, the average time is...

Average Time = (4.11 + 4.03 + 4.06) / 3

                        = 12.2 / 3

                        = 4.07 s

For a distance of 30 cm, the average time is...

Average Time = (6.07 + 5.99 + 6.03) / 3

                        = 18.09 / 3

                        = 6.03 s
