I have a clock at home that chimes on every hour and half hour mark. On whole hour marks it chimes once for each hour, and on half hour marks it chimes only once.

One night I was wakened suddenly and realized the the clock had chimed, but I did not know how many times. As I lay awake thinking about nothing in particular I heard the clock chime once and started wondering what time it was.

What is the longest amount of time I would have to lie awake before I knew for sure what time it was?

The longest uou would have to stay up 1:30 hours... If you did not hear how many times it chimed in the begining, who is to say that it wasnt 12? Then it would chime once at 12:30, once at 1, and once again at 1:30... only then could you be sure of what time it is...
