Expert Answer:

Dear student,

Instantaneous velocity mean change of displacement in extremely small amount time. (in math way, taking[ lim t--->0 (change in displacements/change in time) ].

Instantaneous speed is the same but change displacement  to distance. So,because of very very small change in time, magnitude of distance and displacement will be same for any direction the object is moving.
