Two buses travel to a place at 45kmph and 60kmph respectviely if the second bus takes 5 1/2hours less than the first for the jouirny the length of the journey is

• 990 km
  
  Let x be the length of journey and t time taken by 1st bus
  
  x/45 = t--(1)
  
  x/60 = t - 11/2 ---(2)
  
  (1) -(2)
  
  x/45 - x/60 = 11/2
  15x/(45*60) = 11/2
  
  x = 990 km
