Answer:
We obtain the average velocity instead of the instantaneus velocity.
Explanation:
The problem with calculating speed in this way is that an average speed is being calculated and not an instantaneous speed at a given point.
[tex]V_{average} =\frac{x}{t} \\where:\\x = distance\\t = interval of time[/tex]
To calculate the instantaneous speed, a very small space interval must be measured at a given time.
