@RowdyRathore said in CAT Question Bank  Time, Speed & Distance:
Two trains travelling on the same track, in opposite directions, are separated from each other by a distance of 100 km. One train travels from Bombay to Thane at a speed of 25 kmph and the second train travels from Thane to Bombay at a speed of 15 kmph. At this moment, a crow starts from the first train and flies along the track to the second train, at a speed of 50 kmph, and then flies back to the first train. It repeats this process continually till the two trains collide head on. What is the total distance travelled by the crow in direction of the first train n in the direction of the 2nd second train?
