Hickory dickory dock, the spider went round the clock... (Posted on 2006-05-05) Difficulty: 2 of 5
At exactly six o'clock, a spider started to walk at a constant speed from the hour hand anticlockwise round the edge of the clock face. When it reached the minute hand, it turned round (assume the turn was instantaneous) and walked in the opposite direction at the same constant speed. It reached the minute hand again after 20 minutes. At what time was this second meeting?

This second meeting was at exactly 6:26.

This problem is from the UK Mathematics Trust Intermediate Mathematics Gold Olympiad, Maclaurin paper 2006.
