The pendulum sound will be heard for 15 seconds when it is 6:00 am
GIVEN
Time taken to complete pendulum sound at 12.00 = 33 seconds.
TO FIND
Time taken to complete pendulum sound at 6:00 am
SOLUTION
We can simply solve the above problem as follows -
We know,
Number of intervals between 1th strike and 12th strike = 11 .
Total time taken to complete all intervals = 33 seconds.
Time taken for 1st interval = 33/11 = 3 seconds.
For 6:00 am the number of interval between 1st and 6th stike = 5
So time taken taken = 5×3 = 15 seconds.
Hence, The pendulum sound will be for 15 seconds when it is 6:00 am
