I want to know why, in kinematics, is velocity described as $v = \frac{\Delta x}{\Delta t}$, and why it is not described as any other expression (like a multiplication), why does a division is the one that fits for velocity.
And if there's a way to understand all the other mathematical representations of physical quantities.
