This question tests the ability to apply the formula for calculating the time taken by a train to cross an object (pole or platform), requiring correct handling of distance (train length plus object length) and consistent units for speed and time.
Which of the following statement/ statements is/are true? 1. A 350 meters long train running at a speed of 100 kms/hr takes 25 seconds to cross a platform of length 750 meters. 2. A 750 meters long train running at a speed of 90 kms/hr takes 6 seconds to cross a pole. 3. A 750 meters long train running at a speed of 90 kms/hr takes 40 seconds to cross a platform of length 350 meters.
