A and B starting from x and y simultaneously, heading for y, x respectively. The
ratio of their speeds is 2:1. If each one does 6 return trips (if A return trip is x to y; y to x) how many times would they met each other?

• 9 times.
  
  
  when A completes one return trip, it meets B twice and they are at same point (x) now.
  when A completes second trip, it meets B once while on return journey from y to x.then A at x and B at y .... Starting positions.
  
  so for every 2 return trips of A, they meet 3 times.
  For 6 return trips of A, they will meet 3*3=9 times.
