Velocity can only be described including both

The velocity can be described with both displacement and time. It has direction and magnitude.

Explanation:

The velocity is defined as the rate of change of displacement with time.

V = d/t m/s

It is a vector quantity having magnitude and direction.

The magnitude of the velocity is the speed in the given direction. Hence it is equivalent to the speed of the object in the given direction.

Based on the position of the coordinate, the velocity can be positive or negative.
