A 520 m long train running at a uniform speed, crosses a platform in 40 seconds and a person standing on the platform in 26 seconds. What is the length (in meters) of the platform?
Answer & explanation
Correct answer: option 2
While crossing the man:
Length of train = Distance = Speed × Time
520 = S × 26
S = 20 m/sec
While crossing the platform:
(520 + P) = 20 × 40
P = 800 - 520
P = 280 m
