2.
It takes seconds for a clock to strike o’clock beginning at o’clock precisely. If the strikings are uniformly spaced, how long, in seconds, does it take to strike o’clock?
none of these
Answer: C
Small hint:
Six strikes contain only five time intervals
Big hint:
Twelve strikes contain eleven intervals of the same length
Solution:
There are equal intervals from the first of strikes to the last, so each interval lasts second. Twelve strikes contain such intervals and therefore take seconds.
Thus, the correct answer is C.
