Question
What is the speed of the train? I. The train
crosses the signal pole in 6 seconds. II. The train crosses a platform of equal length in 18 seconds. III. Length of train is 360 meters.Solution
From I , Let the length of train be D and speed of train be s. D = s x 6……..(i) From II , 2D = s x 12 D = 6s …………(ii) From III , D = 360……….(iii) From I & III D = 6s 360 = 6s s = 60 m/s From II & III D = 6s 360 = 6s s = 60 m/s
