Two cars A and B start from two points P and Q respectively towards each other simultaneously. After travelling some distance, at a point R, car A develops engine trouble. It continues to travel at 2/3rd of its usual speed to meet car B at a point S where PR=QS. If the engine trouble had occurred after car A had travelled double the distance it would have met car B at a point T where ST=SQ/9. Find that ratio of speeds of A and B.
