What is average velocity?

The average velocity of an object is the change in the object's displacement per change in the time of motion.

From the graph of Clara's motion, the average velocity of Clara in part A is calculated as follows;

$v = \frac{\Delta x}{\Delta t} = \frac{x_2 \ - \ x_1}{t_2 \ - \ t_1} \\\\ v = \frac{800 \ - \ 0}{10 \ - \ 0} \\\\ v = 80 \ m/s$

The average velocity of Clara in part C is calculated as follows;

$v = \frac{1400\ m \ - \ 800 \ m}{25 \ s \ - \ 20 \ s} \\\\ v = \frac{600 \ m}{5 \ s} \\\\ v = 120 \ m/s$

Thus, we can conclude that Clara is jogging faster during part C of her run.
