Question

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?

• A. 120 m
• B. 360 m
• C. 240 m
• D. 300 m

Answer 1

Answer:

C. 240 m

• 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
