A train moving at a speed of 126 km/h crosses a bridge of length 250 meters in 50 seconds. What is the length of the train?
Show answer & explanation
Correct answer: D
Explanation
Speed = 126 × 5/18 = 35 m/s
Distance covered in 50 seconds = 35 × 50 = 1750 meters
Length of the train = 1750 − 250 = 1500 meters
