Question

Distinguih between average and instataneous velocity

Answer 1

The instantaneous velocity is the specific rate of change of position (or displacement) with respect to time at a single point (x,t).

Average velocity is the average rate of change of position (or displacement) with respect to time over an interval.

Answer 2

$\huge\red{\mid{\fbox{\tt{Aɴsᴡᴇʀ}}\mid}}$

☛Average velocity of a body is defined as the change in position or displacement (Δx) divided by time interval (Δt) in which that displacement occurs. The instantaneous velocity of a body is the velocity of the body at any instant of time or at any point of its path.
