In question it should by “A 300 m long train……”
126 kmph = 126 × 5/18 m/s = 35 m/s
Distance = Speed × Time
(300 + x) = 35 × 24
x = 540 m
Length of the platform (x) is 540 m
Speed = Distance / Time
= [540 m/s] / (5 min × 60 s/min)
= 1.8 m/s
Speed of man is 1.8 m/s
126 kmph = 126 × 5/18 m/s = 35 m/s
Distance = Speed × Time
(300 + x) = 35 × 24
x = 540 m
Length of the platform (x) is 540 m
Speed = Distance / Time
= [540 m/s] / (5 min × 60 s/min)
= 1.8 m/s
Speed of man is 1.8 m/s
