Question
Two trains X and Y whose length are in ratio of 5:8 and
time taken to cross a man standing on a platform is 5:2. If the speed of the train X is 24 km/h find speed of the train Y in m/s.Solution
Let the length of train X = 5a , time = 5b Speed = a/b Let the length of train Y = 8a , time = 2b Speed = 4a/b Ratio of the speed =  = 1 : 4 Speed of train Y = 24 × 4 = 96 km/h in m/s = 96 × 5/18 = 27 m/s ( approx )
