 * A Walking Problem
 * A man taking a walk in the country on turning round saw a friend of his walking $400$ yards behind in his direction.
 * They each walked $200$ yards in a direct line, with their faces towards each other,
 * and you would suppose that they must have met.
 * Yet they found that after their $200$ yards walk that they were still $400$ yards apart.


 * Can you explain?
