problem

A regular tetrahedron is a pyramid with four faces, each of which is an equilateral triangle. Let ABCDABCD be a regular tetrahedron and let PP be the unique point equidistant from points A,B,C,DA,B,C,D. Extend AP→\overrightarrow{AP} to hit face BCDBCD at point QQ. What is the ratio PQ/AQPQ/AQ ?
