To find the rate of change, we need to calculate the slope of the data points.

Step 1: Recall the formula for the slope (rate of change)

The formula for the slope  between two points  and  is given by:

In the context of our problem, the -values represent time (in hours) and the -values represent distance (in kilometers).

Step 2: Choose two points from the table

Let's take the first two points  and

Here , , ,

Step 3: Calculate the slope using the formula
