On a straight line AB of length 120 m, there is a point C which is 40 m away from A and 80 m away from B. P and Q started cycling from C at respective speeds of 5 m/s and 3 m/s, with P moving towards A and Q moving towards B. As soon as they reach A and B, respectively, they start cycling towards B and A and continue moving in a to-and-fro motion. At what distance (in m) from A will they meet each other for the second time?
