  By car 240 km at 60 kmph
  
  Time taken = 240/60 = 4 hr.
  
  By train 240 km at 60 kmph
  
  Time taken = 400/100 = 4 hr.
  
  By bus 240 km at 60 kmph
  
  Time taken = 200/50 = 4 hr.
  
  So total time = 4 + 4 + 4 = 12 hr.
  
  and total speed = 240+400+200 = 840 km
  
  Average speed of the whole journey = 840/12 = 70 kmph.
