Question

calcule a velocidade media de um carro ,que percorre 250km e 5h

Answer 1

Vm = delta S / delta T

Sendo delta S o deslocamento
e o T o tempo.

Vm = 250 / 5

Vm = 50 Km/h

Answer 2

$\large\displaystyle\text{ \mathsf{V_m=\dfrac{\Delta S}{\Delta t} } }$

$\large\displaystyle\text{ \mathsf{ V_m=\dfrac{250\,km}{5\,h}} }$

$\large\displaystyle\text{ \boxed{\boxed{\mathsf{V_m=50\,km/h}} } }$
