Pfv me ajudem nessa questão para a provaaa.
Desde já agradeço <3

Answer 1

Explicação:

v=28km/h

t=2,75h

x=?

x=28.2,75

x=77km

Answer 2

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

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

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

$\Large\displaystyle\begin{gathered} \begin{cases}\sf{V_m=28\,km/h } \\\sf \Delta S=?\,km\\\sf\Delta t=2{,}75\,h\end{cases}\end{gathered}$

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ \Delta S=28\cdot2{,}75} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \therefore\underline{\boxed{\boxed{\sf{\Delta S=77\,km }}}} ~~(\checkmark)\end{gathered} }$
