Explanation:
The average speed is the displacement of a particle divided into a time in which the displacement occurs. Instead, instantaneous speed is the limit of the average speed as the time interval approaches zero.
In physics expressions
[tex]Average speed=\frac{x_{2}-x_{1} }{t_{2}-t_{1} }[/tex]
Instantaneous speed=[tex]lim_{t \to \infty} \frac{x}{t} =\frac{dx}{dt}[/tex]
b) Speed denotes distance traveled divided by time, and instantaneous speed measures how quickly and in which direction does it move
