12. A las 10 de la mañana Elena sale a 100 Km/h de una ciudad A con dirección a Madrid. A la misma hora sale Javier desde otra ciudad B que situada en la misma dirección que A y lo hace a una velocidad de 60 Km/h también con dirección a Madrid. Sabiendo que la distancia en carretera entre A y B es de 132 Km, y suponiendo que los dos van a una velocidad constante todo el camino, contesta a las siguientes preguntas: a) ¿Qué tiempo tardarán en encontrarse Elena y Javier?
b) ¿Qué hora será cuando se encuentren?
c) ¿Qué distancia habrá recorrido cada uno de ellos en ese momento?
