En la terminal del norte de la ciudad de mexico tienen varias corridas hacia el norte del pais la primera sale cada 10 minutos l
creativ13 [48]

Las cuatro carreras saldrán juntas después de 1 hora = 8:00 a.m.

Primera ejecución = 10

Segunda ejecución = 12

Tercera carrera = 15

Cuarta carrera = 30

Dado que las cuatro carreras salieron juntas a las 7:00 a.m. del lunes;

Para calcular el tiempo que los cuatro volverán a funcionar juntos,

Calculamos el mínimo común múltiplo de los cuatro:

Múltiplos de:

10:10, 20, 30, 40, 50, 60, 70, 80, 90

12:12, 24, 36, 48, 60, 72, 84, 96, 108

15:15, 30, 45, 60, 75, 90, 105

30:30, 60, 90, 120, 150, 180, 210

El mínimo común múltiplo de 10, 12, 15 y 30 es 60.

Por lo tanto, las cuatro carreras volverán a salir después de 60 minutos, que es:

60 minutos = 1 hora

7:00 a.m + 1 hora = 8:00 a.m
