Question 585006
Two trains are traveling between two stations at a constant speed of 25kmph.
The stations are 50km apart .
A bird traveling at 100kmph starts its flight along with one train and travels in the same direction until it meets the other train.
 It changes its direction and goes in the reverse direction until it meets the initial train.
 Find the distance traveled by the bird before the two trains collide.
:
Find the time elapsed when trains collide (t)
25t + 25t = 50
50t = 50
t = 1 hr until collision
:
Find how far the bird flies in 1 hr at 100 km/hr, obviously, 100 km for the bird
