A certain clock marks every hour by striking a number of times equal to the hour and the time required a stroke is exactly equal to the time interval between the strokes. At 6 the time elapse between the begining of the first stroke and teh end fo the last stroke is 22 sec. At 12, how many seconds elaspse between the beginning of first stroke and the end of the last stroke?

A 72
B 50
C 48
D 46
E 44


Can you please "mathematicize" the underlined and show the setup and the answer for this question? I am not satisfied with OG's explanation.

Thank you,

Hi, can you please double-check the source and list the correct problem number? This is not PS#110 from OG11. (That one starts "If candy bars...")

Given that you are asking for clarification on wording, I want to read the actual problem, because there are a few little words missing in what you transcribed below and little words can sometimes make a big difference.

Thanks!
