CSAT: Time, Speed & Distance Quiz

Question

A train 150 meters long is running at a speed of 54 km/h.
How much time will it take to cross a 350-meter-long platform?

Accepted Answer

We are given: Length of train = 150 m Length of platform = 350 m Speed = 54 km/h Step 1: Find total distance to be covered. To completely cross the platform, the train must cover: 150 + 350 = 500 meters Step 2: Convert speed into meters per second. Speed in m/s = 54 × (5/18) Speed = 15 m/s Step 3: Use the time formula. Time = Distance ÷ Speed Time = 500 ÷ 15 Time = 33.33 seconds So, the train takes about 33.33 seconds to cross the platform. Among the given options, the closest answer is: 30 seconds (Option A)
