The average velocity of the car traveling south and later returned to the starting point is 0.
Average velocity is defined as the change in displacement per change in the time of motion.
Average velocity is calculated as follows;
[tex]v = \frac{\Delta x}{\Delta t} = \frac{x_2 - x_1}{t}[/tex]
Let the initial displacement of the car, x₁ = 20 m
Let the final displacement of the car, x₂ = 20 m (since the car returned to the starting point).
The average velocity is calculated as;
[tex]v = \frac{x_2 - x_1}{t} = \frac{20 - 20}{5} = 0[/tex]
Thus, the average velocity of the car traveling south and later returned to the starting point is 0.
