A train takes one minute to cross a stationary pole. It takes 240 seconds to cross another train that is 3600 meters long and traveling at 54 kmph.

Find the speed of the first train (in kmph).

Answer :

Final answer:

The speed of the train is 108 kmph.

Explanation:

To find the speed of the train, we need to first calculate the total time it takes the train to cross the stationary pole and the moving train. Let's break it down.

1. Time taken to cross the stationary pole = 1 minute = 60 seconds.

2. Distance to cross the moving train = length of the train + length of the stationary pole = 3600m + 3600m = 7200m.

3. Speed of the train = Distance/Time = 7200m / 240 seconds = 30 m/s = 30 * 3.6 kmph = 108 kmph.

Therefore, the speed of the train is 108 kmph.
