Two trains of same length are running in parallel tracks in the same direction with speed 85 km/hr and 105 km/hr respectively. The latter completely crosses the former in 36 seconds. Find the length of each train (in m).
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 = (105 – 85) × (5/18) = 50/9 m/sec. ∴ Total length = Time × Relative speed ⇒ 2x = (36 × 50)/9 ⇒ x = 100 m
