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 = (70 – 40) × (5/18) = 25/3 m/sec. ∴ Total length = Time × Relative speed ⇒ 2x = (30 × 25)/3 ⇒ x = 125 m
