Answer:
5 times
Step-by-step explanation:
What we need to do here is to find the lowest common multiple of 7,8,11 and 12
This is;
1848
Now, let’s calculate the number of seconds in 3 hours
In 1 hour, we have 3600 seconds
In 3 hours, this will be;
3600 * 3 = 10,800 seconds
So, to find the number of times in which all 4 will toll together, we need to know the number of 1848 seconds in 10,800 seconds
Mathematically, that will be;
10,800/1848 = 5.844
Our answer will be 5 times however
This is because the sixth time they would have sounded together would be more than the 3 hours time frame
