The winning time for a race displayed in the table would be:

A). The winning time increased by an average of 0.4 seconds per year from year 2 to year 4.

Find the increase in winning time:

Given that,

Year                             Winning Time(seconds)

1                                          27.5

2                                         28.4

3                                         28.7

4                                         29.2

5                                         29.44

The total change in the time = (0. + 0.3 + 0.5 + 0.24)/4

= 0.485 seconds

If we round off, it becomes 0.5 seconds.

Therefore, it can be considered that an average of 0.5 seconds changes every year from year 2 to 4.

Thus, option A is the correct answer.
