Sample Medium question 1

A train 120 m long is running at 54 km/h. How much time will it take to cross a platform 300 m long?

  1. 30 seconds
  2. 27 seconds
  3. 28 seconds
  4. 8 seconds
Show answer

Answer: C. Distance = 120 + 300 = 420 m. Speed = 54 × 5/18 = 15 m/s. Time = 420 ÷ 15 = 28 seconds.

Sample Medium question 2

A train 120 m long is running at 72 km/h. How much time will it take to cross a platform 200 m long?

  1. 6 seconds
  2. 15 seconds
  3. 18 seconds
  4. 16 seconds
Show answer

Answer: D. Distance = 120 + 200 = 320 m. Speed = 72 × 5/18 = 20 m/s. Time = 320 ÷ 20 = 16 seconds.

Sample Medium question 3

A train 150 m long is running at 54 km/h. How much time will it take to cross a platform 300 m long?

  1. 30 seconds
  2. 29 seconds
  3. 32 seconds
  4. 10 seconds
Show answer

Answer: A. Distance = 150 + 300 = 450 m. Speed = 54 × 5/18 = 15 m/s. Time = 450 ÷ 15 = 30 seconds.
