The average speed is the total distance traveled divided by the total time:
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
