man walks at speed of 8 km/h 300 mtrs length train crosses man in 30 sec from back, find speed of train

• 44 kmph
  
  if speed of train is x kmph, then
  
  relative speed =(x-8 ) km/hr = (x-8)*5/18 m/sec
  (x-8)*(5/18)*30=300
  x-8=36
  x= 44 km/hr

• 18 Km/hr
  
  relative speed =x-8 km/hr
  x-8*30=300
