Question
A 240 m long train clears a platform of length 160 m in
16 seconds. The ratio of its speed to that of another train is 5:6. Find the length of the second train if it crosses a pole in 21 seconds.Solution
ATQ,
Speed of train 1 = (240 + 160) / 16 = 25 m/sec
Speed of train 2 = (25 Ă— 6) / 5 = 30 m/sec
Length of train 2 = 30 Ă— 21 = 630 m
