The average velocity is the final displacement divided by the total time:

#### Explanation:

The average speed is the total distance traveled divided by the total time, while the average velocity is the final displacement divided by the total time.

The total time is

The distance traveled in the first

The distance traveled in the next

The total distance is

The total displacement is
