5 bells toll at intervals of 5,6,10,15 and 20 seconds respectively. if they toll together at the same time, after how many seconds will they toll together again, for the first time?
The time interval between simultaneous tolling of the bells = LCM(10, 15, 20, 30) seconds = 60 seconds = 1 minute
Hence, the bells will toll together again for the first time after 10:00 am at 10:01 am.
5 bells toll at intervals of 5,6,10,15 and 20 seconds respectively. if they toll together at the same time, after how many seconds will they toll together again, for the first time?
Answer:
They will toll together after 60 seconds
Step-by-step explanation:
The given intervals of 5 bells are 5, 6, 10, 15, and 20 seconds
To find the time after which they will toll together for the first time we need to find the LCM of 5, 6, 10, 15, and 20
The LCM of 5, 6, 10, 15, and 20 is 60
Therefore they will toll together after 60 seconds.
