Answer 2

$\Large\displaystyle\begin{gathered}\tt(I)~\blue{ \sf F\acute ormula:}\end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\sf{V_m=\frac{\Delta S}{\Delta t} }}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt(II)~\blue{\sf{Dados: }} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{\begin{cases}\sf V_m=?\,km/h\\\sf\Delta S=200\,km\\\sf\Delta t=2\,h\end{cases} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt(III)~\blue{\sf{Soluc_{\!\!,}\tilde ao: }} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{ V_m=\frac{200\,km}{2\,h}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\red{\underline{\boxed{\boxed{\sf{ V_m=100\,km/h} }}}}~~(\checkmark)\end{gathered} }$
