Imagine a clock that does not have any hands or numbers on it, but it has a chimer.
If the time is 1 o'clock, it chimes once. If the time is 2 o'clock, it chimes twice, and so forth. The time gap between any two chimes is 3 seconds.
How many seconds would it take you to know the time, after the first chime is heard, if it is 3 o'clock?
