A train 180 meters long running at 72 km/h crosses a modern platform in 20 seconds. Find the length of the platform.
Correct Answer: Option A
Explanation:
Speed of train = 72 * (5/18) = 20 m/s. Total distance covered in 20 seconds = 20 * 20 = 400 meters. Length of platform = Total distance - Length of train = 400 - 180 = 220 meters.
Speed of train = 72 * (5/18) = 20 m/s. Total distance covered in 20 seconds = 20 * 20 = 400 meters. Length of platform = Total distance - Length of train = 400 - 180 = 220 meters.

A train 150 meters long passes a platform 250 meters long in 20 seconds. Find the speed of the train in km/h.
Correct Answer: Option D
Explanation:
Total distance = 150 + 250 = 400 meters. Speed = 400 / 20 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.
Total distance = 150 + 250 = 400 meters. Speed = 400 / 20 = 20 m/s. In km/h = 20 * (18/5) = 72 km/h.
