Instantaneous speed is the velocity of an object at a certain time. For example:- Suppose you are driving in a car and the speedometer constantly varies; this is because the speedometer gives speed at a particular moment of time.
However we attain speeds in excess of 40,000kph, we will have to ramp up to (and down from) them patiently. Rapid acceleration and deceleration can be lethal to the human organism: witness the bodily trauma in car crashes as we go from a mere tens-of-kilometres-per-hour clip to zero in the span of seconds.
