Question

Se um carro faz o movimento a 120 km/h durante 1800 segundos,que distância percorre em km?

Answer 1

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

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

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ \begin{cases}\sf V_m=120\,km/h\\\sf\Delta t=1800\,s=0{,}5\,h\\\sf\Delta S=?\,km\end{cases}} \end{gathered} }$

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ \Delta S=120\cdot0{,}5} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\underline{\boxed{\boxed{\sf{ \Delta S=60\,km}}}}~~(\checkmark) \end{gathered} }$
