Answer 1

Answer:

$v_{avg} =\frac{x_{f}-x_{i}}{t_{f}-t_{i}}$

Step-by-step explanation:

Average velocity is change in position over change in time.

$v_{avg} =\frac{x_{f}-x_{i}}{t_{f}-t_{i}}$

Average speed is distance over time.

$r_{avg}=\frac{d}{t}$

Answer 2

The formula is used to calculate average velocity is

$\rm Average \ velocity = \dfrac{x_f-x_i}{t_f-t_i}$.

We have to determine

Which formula is used to calculate average velocity?

What is average velocity?

The average velocity is defined as the change in displacement and change in a time interval.

The formula is used to calculate average velocity is;

$\rm Average \ velocity = \dfrac{Change \ in \ displacement }{Change \ in \ time}\\\\Average \ velocity = \dfrac{x_f-x_i}{t_f-t_i}$

Where $\rm x_f$ represent the final displacement, $\rm x_i$ initial displacement,

$\rm t_f$ represent final time and $\rm t_i$ represent initial time.

Hence, the formula is used to calculate average velocity is

$\rm Average \ velocity = \dfrac{x_f-x_i}{t_f-t_i}$.
