Tried to expand. Not sure what else I can add.
'''Average velocity''' is the average of an object's [[velocity]] over a period of time. The smaller the time span of an average velocity, the closer it is to [[instantaneous velocity]]. It can be found by calculating the dispersement of an object by the time taken for that displace to occur.

Average velocity is written mathematically as
<math>\bar{v} \equiv \frac{\Delta x}{\Delta t}\equiv \frac{x_f-x_i}{t_f-t_i}</math>
where <math>\bar{v}</math> is the average velocity and <math>x_i</math> and <math>x_f</math> are the initial and final positions and <math>t_i</math> and <math>t_f</math> are the initial and final times<ref>http://theory.uwinnipeg.ca/physics/onedim/node3.html</ref>.
