Question

Two men left simultaneously from two places P and Q. One of them left P for Q and the other left Q for P.B other 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 interns of d1 and d2. (A.2d1-d2 B.3d1-d2 C.4d1-d2 D.5d1-d2)

Answer 1

Ok so above I show the distances traveled by P and Q at each time they meet
Let the times they meet be T1 and T2
Let the speed of P and Q be p and q.

Now set up some equations using the identity: distance = rate * time
....
D = 3d1-d2
