Problema razonado: Aplicación de variaciones inversas.
El tiempo que un avión se toma para volar desde Canadá a China varía inversamente con la rapidez a la cual viaja el avión. Si el viaje toma 13 horas a una velocidad con magnitud de 950 km/h, ¿Cuánto tiempo tomará un el mismo viaje si se vuela con una rapidez de 650 km/h?
