However, the riddle is not completely answered. 1 + 1/2pi (away from
the south pole) is correct, but there are others. For example 1 +
1/4pi also works, since the 1 mile east would take the traveler twice
"around the world" and back to the same spot. In general, we could
say that any point 1 + 1/2npi (n a natural number) will satisfy the
riddle. Thanks for playing, we have some lovely parting gifts.
