A train running at speed of 150 km/hr crosses a 300 m long platform in 30 seconds. What is the length of the train in meters ?

950 m

Total distance traveled by train to cross a platform = Length of train(T) + Length of platform = (T + 300) m

Speed of train = 150 × \(\frac{5}{18}\) m/sec

Time = 30 sec.

⇒ Distance = Speed × Time

⇒ (T + 300) = 150 × \(\frac{5}{18}\) × 30

⇒ (T + 300) = 1250

⇒ T = 1250 - 300 = 950
