at 12:00 j starts to walk from his house at 6kmph. at 13:30 p follows him from j's house on his bicycle at 8kmph.when will j be 3km behind p

• J will cover 9 km b/w (12-13:30)
  now P start at 13:30
  we have to find P-J=3
  total distance travelled by each of them in each hour as follows
  13:30 14:30 15:30 16:30 17:30 18:30 19:30
  J 9 15 21 27 33 39 45
  P 0 8 16 24 32 40 48
  so at 19:30
  P-J=48-45=3 which satisfied the desired cond...
  ans is 19:30
