Question

Qual a velocidade de um carro que percorre 4800m em 80min?

Resposta em km/h e m/s

Answer 1

$\Large\boxed{\begin{array}{l}\underline{\rm Vamos\,encontrar\,a\,resposta}\\\underline{\rm\,em\,m/s\,para\,converter\,em\,km/h}\\\sf \Delta\,s=4800\,m\\\sf\Delta\,t=80\,min\cdot60=4800s\\\sf v=\dfrac{\Delta\,s}{\Delta\,t}\\\\\sf v=\dfrac{4800}{4800}\\\\\sf v=1\,m/s\\\sf v=1\,m/s\times3,6=3,6\,km/h\end{array}}$
