Average speed is defined as the total distance traveled by a body divided by the total time taken to cover that distance. It gives an overall measure of how fast an object moved during a complete journey when its speed was changing. Mathematically, it is expressed as: $$\text{Average Speed} = \frac{\text{Total Distance Traveled}}{\text{Total Time Taken}}$$\nThe SI unit of average speed is meter per second ($\text{m/s}$). It is a scalar quantity because it considers total distance without any specific direction.
