A and B travel from there house on MR road... having speed of A = 20km/hr and Speed Of B= 40km/hr For 'A' after travelling for 2hours 'A' encounters a T junctions and he takes left from the junctions and travels for another two our... where as 'B' after reaching same junction takes right. both 'A' and 'B' travels travel for equal time. what is the difference between the two A and B in km after completion of four hours of their journey each respectively.

• A reched T in 2 hrs whereas B reached in 1 hr.
  after 2 hrs from junction T, A moved (20*2)km=40 km to the left.
  after 1 hr from junction T, B moved (40*3)km= 120 km to the right.
  thus distance between A and B after 4hrs= 40+120 = 160 km (Ans)

• @Mr/Ms.Honey they r starting from the same point.
  check this figure to get a rough idea.
  
  A_ _T_ _ _ _ _ _B
  l
  l
  starting pt.
  
  assume each _ is equal to 20 km

  A(final)

  | 40km

  A,B--------

  |
  | 120km

  B
  
  therefore 160km
