Question

6) A velocidade média de um carro é de 72Km/h. Em quanto tempo ele anda 252km?

Answer 1

Explicação:

v=72km/h

x=252km

t=?

t=x/v

t=252/72

t=3,5h

Answer 2

$\Large\displaystyle\text{ \begin{gathered} \tt{ V_m=\dfrac{\Delta S}{\Delta t}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt{\Delta t=\dfrac{\Delta S}{V_m} } \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \tt{ \Delta t=\dfrac{252}{72}} \end{gathered} }$

$\Large\displaystyle\text{ \begin{gathered} \boxed{\boxed{\tt{ \Delta t=3{,}5\,h}}} \end{gathered} }$
