One night, I was awakened by a single chime. I knew for some reason that the single chime I heard was not the last chime of an hourly chime, but I was too tired to get out of bed to see exactly what time it was.
What would be the longest time I would have to wait to be sure of exactly what time it was? What would be the shortest time I would need to wait?
The longest I would have to wait would be 1 1/2 hours. The shortest time I would have to wait is 15 minutes.
