To find out when the bells ring at the same time between 8:00 am, we need to find the least common multiple (LCM) of 30 minutes and 40 minutes.

The LCM of 30 and 40 is 120 minutes.

This means that every 120 minutes, or every 2 hours, both bells will ring simultaneously.

So, the bells will ring at the same time between 8:00 am at 8:00 am + 2 hours = 10:00 am.
