Formula: Unaccelerated Motion Traveled distance Velocity Time
$$\class{red}{\Delta x} ~=~ \class{blue}{v} \, \Delta t$$
$$\class{red}{\Delta x} ~=~ \class{blue}{v} \, \Delta t$$
$$\class{blue}{v} ~=~ \frac{ \class{red}{\Delta x} }{ \Delta t }$$
$$\Delta t ~=~ \frac{ \class{red}{\Delta x} }{ \class{blue}{v} }$$
Traveled distance
$$ \class{red}{\Delta x} $$ Unit $$ \frac{\mathrm m}{\mathrm s} $$
The traveled distance \(\Delta x = x_2 - x_1 \) from the position \(x(t_1) = x_1\) to the position \(x(t_2) = x_2\) is covered by the body within the time span \(\Delta t = t_2 - t_1 \).
Velocity
$$ \class{blue}{\boldsymbol v} $$ Unit $$ \frac{\mathrm m}{\mathrm s} $$
Constant (unchangeable) speed of the body.
Time
$$ \Delta t $$ Unit $$ \mathrm{s} $$
Time span \( \Delta t = t_2 - t_1\) is the time elapsed between the time \(t_2\) and \(t_1\).
