To find out how much time it will take for the clock to strike 11 o'clock, we need to understand the relationship between the number of strikes and the time it takes for those strikes.
1. Understand the question:
- The clock takes 7 seconds to strike 4 o'clock.
- We need to find out how much time it will take to strike 11 o'clock.
2. Calculate the number of strikes between 4 o'clock and 11 o'clock:
- The number of strikes represents the number of hours that have passed.
- From 4 o'clock to 11 o'clock, there are 7 strikes (5, 6, 7, 8, 9, 10, 11).
3. Calculate the time it takes for each strike:
- Since it takes 7 seconds to strike 4 o'clock, we can calculate the time it takes for each strike by dividing 7 seconds by the number of strikes.
- Time per strike = 7 seconds / 7 strikes = 1 second per strike.
4. Calculate the total time it will take to strike 11 o'clock:
- To find the total time, we need to multiply the time per strike (1 second) by the number of strikes (7 strikes).
- Total time = 1 second per strike * 7 strikes = 7 seconds.
5. Compare the calculated time with the given options:
- The calculated time is 7 seconds.
- Among the given options, option 'D' states 23.33 seconds, which is not the correct answer.
- Option 'A' states 18 seconds, option 'B' states 20 seconds, option 'C' states 19.25 seconds, and option 'E' states 14 seconds.
- None of these options match the calculated time of 7 seconds.
Therefore, none of the given options are correct and the correct answer is not provided.
