answered-by-expert Expert Answer

Instantaneous Speed – When an object is moving with variable speed, then the  speed of an object at any instant of time is called instantaneous speed.

Instantaneous Velocity – It is defined as limit of the average velocity as the time interval ?t becomes infinitesimally small.
                                                   Instantaneous Velocity =
                                                                                         = 
       The value of instantaneous velocity can be obtained either graphically or numerically.
