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.
There are other, simpler ways to find the instantaneous speed of a moving object. On a distance-time graph, speed corresponds to slope and thus the instantaneous speed of an object with non-constant speed can be found from the slope of a line tangent to its curve. We'll deal with this later in this book.
