Explanation:

Step1: Calculate words per minute

For Alan in Data Table 1:
First minute: \(45\) words. Second minute: \(45\times2 = 90\) words. Third minute: \(45\times3=135\) words.
For David in Data Table 1:
First minute: \(40\) words. Second minute: \(40 + 38=78\) words. Third minute: \(40+38 + 51=129\) words.

Step2: Check other tables
