Answer:

After 90 seconds in every 90 seconds thereafter

Step by step explanation

✓First Bell will toll at intervals of 15 seconds; second in 18 seconds and third in 45 seconds.

✓The first time that all the bells toll together will be the least common multiple (LCM)of 15 18 and 45.

✓LCM of 15, 28, 45 =90

✓The first time that all the bell will toll together will be at 90 seconds.

✓It is also clear that the second time the bells toll together will be at 180 seconds then at 270 seconds and so on.

✓Hence the belt with call after 90 seconds in every 90 seconds thereafter.

Simultaneous tolling interval(seconds): 90, 180, 270 etc
