Question

o ciclista percorreu 50km e 1h e 15 min qual a velocidade media exercida por ele?

Answer 1

$\mathsf{V_{m} = \frac{\Delta S}{\Delta t}}$

$\mathsf{\Delta t = 1h15min} \\ \mathsf{\Delta t = 1h + (\frac{15}{60})} \\ \\ \mathsf{\Delta t = 1h + 0,25h} \\ \mathsf{\Delta t = 1,25h}$

$\mathsf{V_{m} = \frac{50}{1,25}} \\ \\ \boxed{\boxed{\mathsf{V_{m} = 40Km/h}}}$
