Solution
11 seconds — The trick here is to count the intervals between strikes, not the strikes themselves. For 6 strikes, there are 5 intervals (e.g., Strike 1_Interval 1_Strike 2_Interval 2_Strike 3_Interval 3_Strike 4_Interval 4_Strike 5_Interval 5_Strike 6). Since these 5 intervals take 5 seconds, each interval takes 1 second (5 seconds / 5 intervals = 1 second/interval).
To strike 12 times, there will be 11 intervals (12 - 1 = 11 intervals). Therefore, 11 intervals multiplied by 1 second per interval equals 11 seconds.
