Question

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

Accepted Answer

Option B. 240 m. Answer & Solution Answer: Option B Solution: & Speed = 54 × 518 \, m/sec = 15\, m/sec & Length\, of\, the\, train = ( 15 × 20 ) m = 300\, m & Let\, the\, length\, of\, the\, platform\, be\,x\, metres & Then,\, x + 30036 = 15 & x + 300 = 540 & x = 240\, m
