Question

formula for velocity​

Answer 1

distance upon time

distance divided by time

Answer 2

By definition of Velocity, It is equal to the time rate of change of position of an object.

$\\ \boxed{ \vec v = \lim_{ \triangle t \to0} \frac{ \triangle r}{ \triangle t} = \frac{d \vec r}{dt} }$

Therefore, the average velocity can be given as:

$\boxed{v_{avg} = \frac{ \triangle r}{ \triangle t} }$
