Multiple Chоice Questiоn 7 Twо trаins аre on the sаme track and are traveling towards each other. The speed of one of the trains is and the speed of the other train is . The distance between the trains two trains is . Starting at this instant, a bird flies from the first train to the second. Once it reaches the second train, it immediately turns around and flies back to the first train – and so on until the trains collide. What is the total distance travelled by the bird? The speed of the bird is . Hint: think in terms of relative motion - it makes this problem so much easier!
