Question

qual a velocidade média de um movel que percorre 280 km em 5 horas? ​

Answer 1

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

$\Large\displaystyle\text{ \begin{gathered} \sf{V_m=\frac{280\,km}{5\,h} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\sf{V_m=56\,km/h} } \end{gathered} }$
