A train running at a speed of 36 kmph crosses an electric pole in 12 seconds.
A train running at a speed of 36 kmph crosses an electric pole in 12 seconds. In how much time will it cross a 370 m long platform?
Answer/Solution
49 min
Steps/Work
E
49 min
Let the length of the train be x m.
When a train crosses an electric pole, the distance covered is its own length.
So, x = 12 * 36 * 5 /18 m = 120 m.
Time taken to cross the platform = (120 +370)/ 36 * 5/18 = 49 min.
