A train 110 meters long passing a platform 290 meters long requires exactly 20 seconds. What is the speed of the train in km/h? MCQ with Answer and Explanation

Explanation:
Speed of train = 220 / 11 = 20 m/s. Total distance to cross platform = 220 + 300 = 520 meters. Time taken = 520 / 20 = 26 seconds.

Explanation:
Total distance = 150 + 250 = 400 meters. Speed = 72 * (5/18) = 20 m/s. Time taken = 400 / 20 = 20 seconds.

Explanation:
Time difference = 15 - (-5) = 20 minutes = 20/60 = 1/3 hours. Let distance be d. d/5 - d/7.5 = 1/3 => (1.5d - d) / 7.5 = 1/3 => 0.5d / 7.5 = 1/3 => d / 15 = 1/3 => d = 5 km.
