Two men left simultaneously from two places P and Q. One of them left P for A and the other left Q for P. Both travelled at uniform velocities. Having arrived at their destinations they turned back to their starting points without stopping. First time they met on their onward journey d1 km from P and the second time on their return journey they met d2 km from Q. If d is the distance between P and Q then find d in terms of d1 and d2.
