David Bodycombe
- David went for a swim in the circular lake on
the island. He swam to about the middle of the lake and felt something
tentacle-like tugging at his feet and he went sub-aqua, but fortunately
the others saved him. Here's how they did it.
Each of the other three, on the perimeter of
the lake, made a guess as to where he sank.
Angela drew a line from her sun lounger on the
circumference of the lake, through the spot where she thought he'd drowned
and continued the line until it reached the other edge of the
lake.
Chris did the same thing from a different point
and so did Paul. Because of human error all 3 lines didn't meet at exactly
the same point. These 3 lines formed a little triangle in the middle of
the lake. While David was struggling with the octopus he was trying to
work out the probability that he was in the triangle that they were
forming in their minds. What was that probability?

Chris Maslanka's listeners' puzzle
- Orangatanga air base lies on an island on
the equator. Group Captain Boggles has just 2 identical Boing 497's with
identical tanks, air speed etc. He has, however, a limitless supply of
fuel and he wants to fly once around the world - a distance of 25,000
miles. Unfortunately the range of the Boing 497 is less than this.
Nevertheless he hits upon the idea of using one of the planes to refuel
the other in mid air. The one doing the refuelling can't fly too far from
base as it needs to get back there. What is the smallest the range of the
Boing 497 can be if it is only just possible to do it?
