A clock strikes 12 talking 48 s. In order to strikes 3 at the same rate, the time taken is?

There are 11 intervals when the clock strikes 12.
Time taken for 11 intervals = 48 s
∴ Time taken for 1 interval = (48/11)s
In order to strike 3, there are 2 intervals, for which the time taken = (48/11) x 2) = 8⁸/₁₁ s
