Answer

Answer:

Second table (Time: 5, 6, 7, 8, 9; Speed: 45, 47, 49, 48, 47)

Explanation:

Step1: Analyze first table

Speed decreases from 45 to 43 to 41, then increases slightly to 42 and 43. But it starts decreasing right away.

Step2: Analyze second table

Speed starts at 45, increases to 47 at 6 minutes and 49 at 7 minutes, then decreases to 48 at 8 minutes and 47 at 9 minutes, which meets the criteria of increasing then decreasing.

Step3: Analyze third table

Speed stays at 45 for 5 - 6 - 7 minutes then decreases, no initial increase.

Step4: Analyze fourth table

Speed decreases from 45 to 43 to 41 and stays at 41, no increase.
