Explanation
To find when the bells will toll together again, we need to find the least common multiple (LCM) of the time intervals between their tolls.
The time intervals between their tolls are: 8 minutes, 15 minutes, and 24 minutes.
The LCM of 8, 15, and 24 is 120.
So, the bells will toll together again after 120 minutes, which is 2 hours.
If they tolled together at 5:00 PM, then they will toll together again at 7:00 PM.
