Ban, tag and black are neighborhood dogs. ban consistently barks every 4 minutes, tag every 3 minutes, and black every 5 minutes. if they barked simultaneously at 11 p. m , at what time will they bark simultaneously again?

Step-by-step explanation:

Just find the LCM or least common multiple of the minute-intervals of their barking. Then, add it to 11 p.m. to know the answer.

Finding the time when the dogs bark together:

They bark together every 60 minutes (1 hour).

11 p.m. + 1 hour = 12 a.m.
