To different individuals, it may or may not have any significance. The quantity is
typically referred to as "speed", and you're free to decide for yourself whether it
has any relevance in your life.
The rate of change of position is the velocity. The velocity at a specific point in time is called the instantaneous velocity.
Change in velocity divided by time is acceleration, but velocity divided by time has no particular significance.
Velocity = distance divided by time / Velocity = average speed over time / Acceleration = (change of) velocity divided by time elapsed Change in velocity = final velocity "minus" initial velocity divided by time elapsed
speed, time, distance
Acceleration is an increase in change in speed over time of an object, and deceleration is a decrease in the change in speed over time of an object. -aerol-
A person walking is an example of a change in position over time.
velocity
The answer is displacement.
Changes in position over time is motion, and the rate of change may be velocity or speed.
Speed --- actually, if your question is 'position' over time, there is no answer since position is a vector quantity. And position divided by time will still yield a vector quantity-- velocity. If the question asks for change in distance over time, then the answer is speed. --gh ---

Velocity is the rate of change of position over time.
In the question, "an object's change in position...over...time" is a perfectly reasonable definition of velocity.
a continuous change in position is called Motion
movement
speed.
