Answer 2

Answer:

If they all ring out at 12 a.m. then they will ring together again at 4 p.m.

Step-by-step explanation:

Here, we have to take the LCM of 16, 24 and 40.

LCM(16,24,40) = 240

So, all the bells we ring together at an interval of 240 minutes = 240/60 hours = 4 hours

If they all ring out at 12 a.m. then they will ring together again at 4 p.m.
