The velocity in which a body covers equal displacements in intervals of time is constant velocity.

Here's why:

* Velocity is a vector quantity that includes both speed and direction.

* Constant velocity means the object is moving at the same speed in the same direction.

If an object covers equal displacements in equal intervals of time, it means that it's moving at a constant rate, covering the same distance in the same amount of time. This signifies that its velocity is constant.

Example:

Imagine a car traveling on a straight road at 60 km/h. If it covers 1 km every minute, it's moving at a constant velocity. The car is maintaining the same speed and direction.
