Answer / Jitendra Kumar Verma
Let's denote the lengths of both trains as L1 for the faster train (300 meters) and L2 for the slower train (200 meters). The total distance between them is D = L1 + L2 - 2 km = 502 meters. To find out how long it takes for both trains to cross each other, divide this total distance by their relative speed: Time = D / (L1 - L2) = 502m / (300m - 200m) = 502m / 100m = 5.02 hours.
