Triangle, Square, & Other Polygon Puzzles 93- THE RUSSIAN MOTORCYCLISTS
Two Army motorcyclists, on the road at Adjbkmlprzll, wish to go to
Brczrtwxy, which, for the sake of brevity, are marked in the accompanying
map as A and B. Now, Pipipoff said: "I shall go to D, which is six miles, and
~--------~~--------~then take the straight road to B, another fifteen miles." But Sliponsky thought
he would try the upper road by way of C. Curiously enough, they found on
reference to their cyclometers that the distance either way was exactly the
same. This being so, they ought to have been able easily to answer the
General's simple question, "How far is it from A to C?"
It can be done in the head in a few moments, if you only know how. Can
the reader state correctly the distance?- THOSE RUSSIAN CYCLISTS AGAIN
Here is another little experience of the two Russian Army motorcyclists that
I described in our last puzzle. In the section from a map given in our illustra-
tion on page 94 we are shown three long straight roads, forming a right-angled
triangle. The General asked the two men how far it was from A to B. Pipipoff
replied that all he knew was that in riding right round the triangle, from A to B,
from there to C and home to A, his cyclometer registered exactly sixty miles,
while Sliponsky could only say that he happened to know that C was exactly
