ayuda plis porfas me urge no respondas por los puntos o te reporto pliss si no sabes no respondas ​

Answer 1

Respuesta:

$v_{f} = v_{0} + a.t \\ \\ v_{f} = a.t$

$60 \frac{km}{h} = ( \frac{20 \: km}{ {h}^{2} } )(_{t}) \\ \\ \\ \\ ( \frac{20 \: km \: }{ {h}^{2} } )(_{t}) = 60 \frac{km}{h}$

$t = \frac{60 \frac{k}{m} }{ 20\frac{km}{ {h}^{2} } }$

$t = 3 \frac{km. {h}^{2} }{h. \: km}$

$t = 3h$
