Solution Steps

Step 1: Find the winning time for 2014

The winning time for 2014 is 38 minutes.

Step 2: Find the winning time for 2015

The winning time for 2015 is 40 minutes.

Step 3: Calculate the change in winning time

The change in winning time from 2014 to 2015 is 40 - 38 = 2 minutes.

Step 4: Calculate the rate of change

The rate of change is the change in winning time divided by the change in year. The change in year is 2015 - 2014 = 1 year. Therefore, the rate of change is 2 minutes / 1 year = 2 minutes per year.
