Question

Qual é a velocidade escalar média, em km/h ,De uma pessoa que percorre ,a Pé , 1200m em 20 minutos ?

Answer 1

20min=1200s

v=d/t

v=1200/1200

v=1m/s

1.3,6=3,6km/h

Espero ajudar❤

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \sf{ 1200\,m\rightarrow1{,}2\,km} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \sf{ 20\,min\rightarrow\frac{1}{3}\,h} \end{gathered} }$

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

$\Large\displaystyle\text{ \begin{gathered} \sf{ V_m=\frac{1{,}2\,km}{\dfrac{1}{3}\,h}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered}\boxed{\boxed{ \sf{ V_m=3{,}6\,km/h }}}\end{gathered} }$
