With a speed of 60 kmph a train crosses a pole in 30 seconds. The length of the train is
Answer & explanation
Correct answer: option 4
Speed = \(\frac{ Distance}{ Time}\)
Let the length of the train be x
60 x \(\frac{ 5}{18 }\) = \(\frac{x}{30}\)
10 x \(\frac{ 5}{3 }\) = \(\frac{x}{30}\)
\(\frac{50}{3 }\) = \(\frac{x}{30}\)
x = 500 m
