Explanation:

The term average here is defined as the average of the initial and final quantity.

For example, in the case of speed, the average speed is the sum of initial and final speed by 2.

The velocity of an object is defined as the displacement by time. Whereas speed is expressed as the distance between two successive positions of the body to the time interval it took to travel.

               Velocity,        V = D / t        m/s

                Speed,          s = d /t          m/s          

Velocity is a vector quantity that has a magnitude and direction.

The speed is a scalar quantity having only the magnitude.

At any instant of time, the magnitude of the velocity is always equal to the magnitude of the speed. The magnitude of velocity, |v | = magnitude of speed, |v|. The magnitude is always positive

Similarly, this is the case with displacement and distance.

The position vector is the location of the vector from the origin of the coordinate.
