 * The Despatch-Rider in Flanders
 * A despatch-rider on horseback, somewhere in Flanders, had to ride with all possible speed from $A$ to $B$.
 * The distances are marked on the map.

 * Now, he can ride just twice as as fast over the soft turf (the shaded bit) as he can ride over the loose sand.
 * Can you show what is the quickest possible route for him to take?


 * This is just one of those practical problems with which the soldier is faced from day to day when on active service.
 * Important results may hang on the rider taking the right or the wrong route.
 * Which way would you have gone?
 * Of course, the turf and the sand extend for miles to the right and the left with the same respective depths of three miles and two miles,
 * so there is no trick in the puzzle.
