Explicación:
t = d/v
[tex]t = \frac{ \frac{20km}{1} }{ \frac{80km}{h} } = \\ t = \frac{20km \times h}{80km} = \\ t = \frac{20 \times h}{80} = \\ t = \frac{1h}{4} \\ \\ 1h < = = > 60m \\ \frac{1h}{4} < = = > x \\ \\ \frac{60m \times \frac{1h}{4} }{1h} = \\ \frac{60m \times \frac{1}{4} }{1} = \frac{60m}{4} = 15m[/tex]
