Q. A and B Start from two places X and Y respectively, that are 60km apart. If A and B travel at uniform speed of 80km and 20km per hour respectively, and return back immediately to their respective places after reaching Y and X respectively, then how often and what distance from X, shall they meet.

• First time they will meet after 60/100 hrs from start = 36 min from start
  and at a distance 80*60/100 = 48 kms from X.
