Responde el siguiente problema de lógica: Al mirar el reloj, vemos que la manecilla de los minutos apunta a un número que casual

ANTONII [103]

Answer: 11:50

Step-by-step explanation:

Ok, la manecilla de los minutos apunta al numero X.

si la ora es Y, entonces Y + X = 12:00

podemos asumir que Y es 11:y

y es la cantidad de minutos despues de las 11, es un numero entre 0 y 59 (por que una hora solo puede tener 60 minutos)

Si la manecilla de los minutos apunta al numero 6 por ejemplo, entoces:

y = 11:30 y X = 6 min

X + y = 11:30 + 0:06 = 11:36

Así funciona.

la equacion es:

y = 5*X

y tambien queremos que:

X + y = 60min

reemplazo y por lo de la equacion de arriba:

X + y = X + 5*X = 6X = 60min

X = 10

Si la manecilla apunta al 10, tenemos que:

y = 11:50 y X = 10min

y + X = 11:50 + 0:10 = 12:00

Entonces podemos concluir que la hora es 11:50.
