a bird is sitting on train A is moving towards east with a velocity of 300 km per hour and another train of same speed moving in West direction on the same track when the trains are 6 km apart the birds starts flying with a velocity of 30 km per hour with respect to the ground towards B after touching B it returns back to A and continue repeating this process until the trains collide in this process the total distance covered by the bird is

Answer 1

Hey here's ur ANSWER  . Time taken by trains to meet = time taken by the bird to fly  6/(300+300) = D/30 D = 180/600 km  = 0.3 km = 300 m ______________________________  HOPE IT HELPS

Answer 2

solution:

Time taken to the trains = time taken to the bird to fly 6/(300+300)=d/30,

d=30/100

  =0.3km,

d=300m
