Question

Three bells ring at intervals of 10,20,30 minutes. If they ring together at 11.am, at what time will they next ring together?

Answer 1

Answer:

12 pm

Step-by-step explanation:

First, find the lcm of 10,20,30 which is 60

second, We found 60 mins so convert 60 into hours

60mins=1hour

So, this means that after every 1 hour the bells ring together

So the next hour is 12 pm or you can add 1 hour to 11 am

which is 12 pm :)
