Thanks for asking us a question in Ask the Expert section of TopperLearning.com.


In this question you have asked "Two trains A and B, each of length 100 m ,are running on parallel tracks .one overtakes the other in 20s and one
crosses the other in 0 s . calculate the velocities of each train" it is given that "one crosses the other in 0 s ", which sounds incomplete( time is given as 0 sec).We would request you to recheck the question you have asked, so that we may answer this to the best of the ability.
