A 725 m long train passes a tunnel 235 m long in 48
seconds. Find the speed of the train.Solution
According to the concept, The train had covered 725 + 235 = 960 m Speed of the train in m/sec = 960/48 ⇒ 20 m/sec Speed of the train in km/h = 20 × (18/5) ⇒ 72 km/h ∴ The speed of the train is 72 km/h.
