Problem:

It takes a pendulum of a clock 7 seconds to strike 4 o’clock. How much time (in seconds) will it take to strike 11 o’clock? Explain in details.


Solution:

Let's analyze the problem and try to find a solution. The clock strikes a number of times equal to the number of hours passed since midnight. At 4 o'clock, the clock strikes 4 times. At 11 o'clock, it strikes 11 times. So, we need to find out how much time it takes for the clock to strike 11 times compared to the time it takes to strike 4 times.


Time taken to strike once:

First, let's calculate the time taken for the clock to strike once. To do that, we can divide the time taken to strike 4 times by 4:


Time taken to strike once = 7 seconds / 4 = 1.75 seconds


Time taken to strike 11 times:

Now that we know how much time it takes for the clock to strike once, we can calculate the time it takes for the clock to strike 11 times:


Time taken to strike 11 times = 1.75 seconds x 11 = 19.25 seconds


Answer:

Therefore, it will take 19.25 seconds for the clock to strike 11 o'clock.
