(It has helped me, and, in fact, a few kids I know if you don't mind,
to represent these abstract lengths (if that's what they are) as steps
a man can walk. If one person walks for 1 step, then 2 ... how far
would this person have got in steps? What about some other person
taking three steps on a straight line?
If you flattened the two shorter paths by "bending" them towards
the 3-step path, what happens?)
