/*
Assume a rectangular region 500m x 15m in dimensions. A road of width 10m runs at the
centre. Surrounding the road are two pavements of width 2m each. Outside the pavements, there
are grassy regions of width 0.5m on each side. There are two zebra crossings on the road,
one at 1/4th the length of the road and the other at 3/4th the length. Let us call the first
crossing A and the second one B.

The origin lies at the bottom left corner of the rectangle. The x co-ordinate increases
from left to right while the y co-ordinate increases from the bottom to top.
