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 – 70) × (5/18) = 125/9 m/sec. ∴ Total length = Time × Relative speed ⇒  2x = (36 × 125)/9 ⇒  x = 250 m
