When two trains cross each other, they cover distance equal to the sum of their lengths with relative speed. Let's take length of each train = x So, total length of both trains = 2x Relative speed = (120 – 80) × (5/18) = 100/9 m/sec. ∴ Total length = Time × Relative speed ⇒ 2x = (36 × 100)/9 ⇒ x = 200 m
