MARIALAURAEntre el punto A y el punto B hay 150 Km. Un coche sale de A hacia B a 10 Km/h y un coche sale de B hacia A a 50 Km/h. si el Kilómetro 0 está en A ¿En qué Km se encontrarán?. Y si el coche B sale 1 hora más tarde.
Un saludo y a estudiar mucho.
Academia OpositasHola Marialaura:
hubo una tutoría de dudas en test psicotécnicos donde trabajamos este tipo de ejercicios.
Debes pensar que la suma de sus velocidades, en este caso, 60 km/h recorriendo toda la distancia desde A a B sería lo mismo que el caso del ejercicio. Es decir, que un coche a 60 km/h tardaría lo mismo en hacer el recorrido de A a B que los otros dos coches en encontrarse yendo uno a 10km/h y el otro a 50km/h.
De esta forma lo verás mucho más fácil para poder resolverlo. Si no lo consigues… te seguiremos ayudando.
Un saludo
PJLa solución que te ha dado CR, esta bien, pero para el caso de que salgan los dos coches a la vez.
En el caso de que A salga una hora antes, debes de calcular el tiempo que tardara el choche a 60 km/h en recorrer 140 km (no 150 km), entonces le aplicas ese tiempo a cada coche para comprobar que da la misma distancia.
OJO!!!!!!!!!! No olvides sumar los 10 km recorridos por el vehículo A durante la primera hora.
Espero que te sirva mi respuesta.
