Two trains are opposite to each other , bird is on one train . Speed of both trains are 25km/hr & 50 km apart . When trains starts(against each other) , bird also start flying from one train to other , till they clash. Speed of bird is 100km/hr . Distance travelled by bird till trains clash. ?

• 100 kms.
  
  Bird kept on flying till two trains met .
  
  Time taken by two trains to meet = 50(25+25) = 1 hr
  
  Distance travelled by bird in 1 hr = 100 kms as speed is 100 kmph.

• relative speed of trains is = 25+25 =50km/hr
  distance between trains = 50km
  time taken to meet = 50/50 = 1hr
  distance traveled by bird in that hour is =100km

• 100km
  relative velocity is 50
  time take to clash=1hour
  distance trevlled by the bird=100

• Speed of bird to that of train is 1:4
  Since train took 2 hrs to complete the journey till then bird would cover 2×100=200 kms
