Question

A train running at the speed of 72 kmph crosses a 260 metre long platform in 23 seconds. What is the length of the train in metres?

• A. 200
• B. 240
• C. 220
• D. 160

Answer 1

Answer:

A. 200

Let length of the train = x Distance = Length of the platform + length of the train = 260 + x Speed = 72 km/hr = 72 x 5/18 = 20 m/sec. Time = 23 seconds, 260+X/20 = 23 or 260 +X = 23 x 20 = 460 :: x = 460 - 260 = 200 metres.
