Correct Answer : C.
First convert speed from km/hr to m/sec So, Speed = 72*(5/18) = 20 m/sec Time = 26 seconds Let the length of the train be x meters. We know, Distance = Speed*Time. [you can remember this formula as remembering DUST = D*ST, Distance=Speed*Time] x+250 = 20*26 => x = 270 meters So length of the goods train is 270 meter View Answer
