To find the average velocity of the car during the last three seconds, you'll need to know the change in position (distance) and the time interval over which this change occurred.

Average velocity (\(v_{\text{avg}}\)) is calculated as:

\[v_{\text{avg}} = \frac{\text{Change in position}}{\text{Time interval}}\]

In this case, the time interval is the last three seconds. Let's assume the car's position at the initial time \(t_0\) is \(x_0\) meters, and at the final time \(t_3\) (three seconds later), the position is \(x_3\) meters.

So, the change in position is:

\[\text{Change in position} = x_3 - x_0\]

Now, we need to know the values of \(x_3\) and \(x_0\) to calculate the change in position.

Once you have the values of \(x_3\) and \(x_0\), you can use the formula for average velocity:

\[v_{\text{avg}} = \frac{x_3 - x_0}{3 \text{ seconds}}\]

Substitute the values of the change in position and the time interval to calculate \(v_{\text{avg}}\). The result will be in units of meters per second (m/s).
