Coincident Clock HandsAppeared in Volume 9/4, November 1996
If the hour hand, minute hand, and second hand of a clock all coincide, it is easy to show that the time must be either noon or midnight. At what times between 12:00:05pm and 11:59:55pm do the three clock hands all lie within the smallest possible angle?
