Question

A clock chimes the hour, every hour on the hour, and once each quarter hour in between.

If you hear it chime once, what is the longest you may have to wait to be sure what time it is?

1h and 30min.In worst case you'll hear the clock at 12'45".After 7 chimes you'll know that is 13'45",because the next one will be for 2 o'clock.

Correct.

No apology needed... I didn't do a very good job of monitoring answers on this one.

I've had problems logging on to the site the last few days.
