It is one of the Powerprep questions, and I am figuring the reason for 11 equal time intervals between strokes. Could someone show a simple solution to the question?
A certain clock marks every hour by striking a number of times equal to the hour, and the time required for a stroke is exactly equal to the time interval between strokes. At 6:00 the time lapse between the beginning of the first strokes and the end of the last stroke is 22 seconds. At 12:00, how many seconds elapse between the beginning of the first stroke and the end of the last stroke?
