Question

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:

$\huge{\mathcal{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}$

Relative velocity b/w trains=(300+300)km/h

=600km/h

Time taken for crash:

$t = \frac{d}{v}$

$t = \frac{6}{600}$

$t = \frac{1}{100} hours \:$

$t = 36seconds$

Velocity of bird=30km/h

$velovity \: of \: bird = 30 \times \frac{5}{18}$

$distance \: travelled \: by \: bird = 30 \times \frac{5}{18} \times 36$

300m
