A train 150 m long is running at a speed of 90 kmph. Time taken by the train to cross a tree is :
Answer & explanation
Correct answer: option 3
Speed = \(\frac{ Distance}{ Time}\)
Time = \(\frac{ Distance}{ Speed}\)
Speed = 90 x \(\frac{5 }{18 }\) = 25 m/s
Time = \(\frac{ 150}{ 25}\)
Time = 6 seconds
