Answer» Correct Answer - Option 3 : 105 Given: Two trains of same length are running on parallel tracks in the same direction at 56 km/h and 44 km/h, respectively. The faster train passes the other train in 63 seconds. Concept used: Time and Distance Calculation Two trains of same length are running on parallel tracks in the same direction at 56 km/h and 44 km/h, respectively. Two trains are running in the same direction Relative speed = 56 km/hr - 44 km/hr Relative speed = 12 km/hr Converting the relative speed in m/sec ⇒ \(12 × \frac{5}{{18}} = \frac{{10}}{3} \ m/\sec \) Time = 63 sec (Given) Distance = Speed × Time Distance = \(63 \times \frac{{10}}{3} = 210\ m\) Length of each train = \(\frac{{210}}{2} = 105\ m\) |
