A train passes a platform in 36 seconds and a man standing on the platform in 20 seconds. If the speed of the train is 54 km/h, what is the length of the platform?

A120 m

B360 m

C240 m

D300 m

Answer:

C. 240 m

Read Explanation:

  • Train Speed: 54 km/h = 15 m/s

  • Train Length: 15 m/s * 20 s = 300 m

  • Total Distance (Train + Platform): 15 m/s * 36 s = 540 m

  • Platform Length: 540 m - 300 m = 240 m
