A train X starts from Meerut at 4 p.m. and reaches Ghaziabad at 5 p.m. while another trainY starts from Ghaziabad at 4 p.m. and reaches Meerut at 5.30 p.m. The two trains will cross each other at: A. 4.36 p.m. B. 4.42 p.m. C. 4.48 p.m. D. 4.50 p.m. Answer Workspace Report Discuss Answer with explanation Answer: Option A Explanation Suppose, the distance between Meerut and Ghaziabad is x km. Time taken by X to cover x km = 1 hour. Time taken by Y to cover x km = 3 2 hours. Speed of X = x kmph, Speed of Y = 2x 3 kmph. Let them meet y hours after 4 p.m. Then, xy + 2xy 3 = x y 1 + 2 3 = 1 y = 3 5 hours = 3 5 x 60 min = 36 min. So, the two trains meet at 4.36 p.m. Workspace
