A 476 m long moving train crosses a pole in 14 sec. The length of a platform is equal to the distance covered by the train in 20 sec. A man crosses the same platform in 7 m and 5 sec. What is the Speed of the man in m/s ?
A) 1.8 m/s
B) 1.4 m/s
C) 1.6 m/s
D) 2 m/s
E) 1.2 m/s
Correct answer:
C) 1.6 m/s

Speed of the traub = \( \frac{476}{14} = 34 m/s\)
Length of the platform = \( 34 \times 20 = 680 m \)
Speed of the man = \( \frac{680}{425} = 1.6 m/s \)
