প্রশ্নে বলা হচ্ছে, প্লাটফর্মে দাঁড়িয়ে একজন লোক লক্ষ্য করলেন যে, একটি ট্রেন 3 সেকেন্ডে তাকে অতিক্রম করলো। বিপরীত দিক হতে আসা একই দৈর্ঘ্যের অপর একটি ট্রেন তাকে 4 সেকেন্ডে অতিক্রম কলে গেল। ট্রেন দুটি পরস্পরকে কত সময়ে অতিক্রম করবে?Let, length of each train be x meterNow, we know that time taken by the train to pass a standing man is the some time to pass the length of its own∴ Speed of the 1st train,

v1 = x3ms-1And speed of the 2nd train v2 = x4ms-1This two train have to pass a distance of (x + x) meter = 2x meter.As opposite direction, we know required time = DistanceVelocity ⇒Time = 2x x3+ x4 = 2x 4x+3x12 = 2x1 × 127x = 3.42 seconds.∴ Time taken by the two trains to cross each other is 3.42 seconds.

A train passes a man in 3 second, and another train from opposite direction pass the man 4 second, both train same length. How long time need to pass the train each other?
