Question

qual a distância percorida por um tem , com velocidade média de 50km/h , em 3 horas ?

Answer 1

velocidade = distância / tempo

50 = d/3

50 x 3 = d

d = 150 km


resposta. 150 km

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \blue{\bf{F\acute{o}rmula :}} \end{gathered} }$

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

$\Large\displaystyle\text{ \begin{gathered} \blue{\bf{Dados: }} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{\begin{cases}\sf V_m=50\,km/h\\\sf \Delta t=3\,h\\\sf\Delta S=?\,km\end{cases} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered}\blue{ \bf{ Soluc_{\!\!,}\tilde{a}o:}} \end{gathered} }$

$\Large\displaystyle\begin{gathered} \sf{ \Delta S=50\cdot 3} \end{gathered}$

$\Large\displaystyle\text{ \begin{gathered}\therefore\green{\underline{\boxed{\boxed{ \sf{\Delta S=150\,km }}}}} ~~(\checkmark)\end{gathered} }$
