The formula for average speed is $\text{average speed} = \frac{\text{total distance}}{\text{total time}}$.
Average speed does not account for changes in velocity or direction.
It is different from average velocity, which considers displacement rather than total distance.
Units for average speed are typically meters per second (m/s) or kilometers per hour (km/h).
In uniform motion, average speed equals instantaneous speed.
