Question

Supondo que um carro gasta 4 horas para percorrer 200km .qual sua velocidade média ?

Answer 1

Dados :

∆S = 200 km

T = 4 h

Vm = ?

Resolução:

Vm = ∆S / T

Vm = 200 / 4

Vm = 50 km/h

RESPOSTA: A SUA VELOCIDADE MÉDIA É DE 50 KM/H.

Answer 2

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

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

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ \begin{cases}\sf V_m=?\,km/h\\\sf \Delta S=200\,km\\\sf\Delta t=4\,h\end{cases}} \end{gathered} }$

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ V_m=\frac{200\,km}{4\,h}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\underline{\boxed{\boxed{\sf{ V_m=50\,km/h}}}}~~(\checkmark)\end{gathered} }$
