A body is said to be at non uniform sped when it equal distance in unequal interval of time irrespective of direction.

A body is said to be at average speed when does not cover equal distance in equal interval of time.

Answer 2

Uniform speed - The speed in which a body travels equal distance in equal interval of time Non Uniform speed - The speed in which a body travels unequal distance in equal interval of time ,Average speed - The total distance covered in total interval of time is called average speed ,Instantaneous speed- The speed of a body at given instant of time is called its Instantaneous speed.
