Answer:

La rapidez del móvil es 12 kilómetros por hora.

Explanation:

Asumamos que el móvil experimenta un movimiento rectilíneo uniforme, cuya ecuación cinemática es la siguiente:

[tex]v = \frac{x}{t}[/tex] (1)

Where:

[tex]x[/tex] - Distancia recorrida, en kilómetros.

[tex]t[/tex] - Tiempo, en horas.

[tex]v[/tex] - Rapidez, en kilómetros por hora.

Si tenemos que [tex]x = 6000\,m[/tex] y [tex]t = 30\,min[/tex], entonces la rapidez del móvil es:

[tex]v = \frac{6000\,m\times \frac{1}{1000}\,\frac{km}{m}}{30\,min \times \frac{1}{60}\,\frac{h}{min} }[/tex]

[tex]v = 12\,\frac{km}{h}[/tex]

La rapidez del móvil es 12 kilómetros por hora.
