What is the Length of Train in Meters?
Answer: (c) 750m
Given – The length of the train = length of platform = X m
and speed of train = 90km/hr
taken time by train across the platform = 1min
Speed into m/sec = 90 x 5/18 = 25m/sec
and time in sec = 1 x 60 = 60 sec.
Distance = speed x time
According to question,
2X = 25 x 60 = 1500
X = 1500/2 = 750m
Hence, the length of the train is 750m
