Convertimos la velocidad a metros por segundos:
[tex]v =10\ \dfrac{\not km}{\not h}\cdot \dfrac{1000\ m}{1\ \not km}\cdot \dfrac{1\ \not h}{3600\ s}[/tex]
[tex]v = \dfrac{10\cdot 1000}{3600}\ m/s[/tex]
[tex]v = \dfrac{10000}{3600}\ m/s[/tex]
[tex]v = \dfrac{100}{36}\ m/s[/tex]
[tex]v = \dfrac{25}{9}\ m/s[/tex]
Luego el tiempo será:
[tex]t = \dfrac{d}{v}[/tex]
[tex]t = \dfrac{200\ m}{\frac{25}{9}\ m/s}[/tex]
[tex]t = 72\ s[/tex]
R/ Demora 72 segundos.
