Question

calcule a velocidade media em m/s de um veiculo que percorre 720km em 300 min

Answer 1

• $\Large\displaystyle\begin{gathered} \sf{F\acute ormula: } \end{gathered}$

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

• $\Large\displaystyle\begin{gathered} \sf{Dados: } \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered} \sf{ \begin{cases}\sf V_m=?\,m/s\\\sf \Delta S=720\,km=720000\,m\\\sf\Delta t=300\,min=18000\,s\end{cases}} \end{gathered} }$

• $\Large\displaystyle\text{ \begin{gathered} \sf{Soluc_{\!\!,}\tilde ao: } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{ V_m=\frac{720000\,m}{18000\,s}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\underline{\boxed{\boxed{\sf{ V_m=40\,m/s}}}}~~(\checkmark)\end{gathered} }$
