A train, 150 m long is running at 90 km/h. How long (in seconds) will it take to clear a platform that is 300 m long?
Answer & explanation
Correct answer: option 2
90km/h = 90 × \(\frac{5 }{18}\) m/sec = 25 m/sec
Time = \(\frac{Distance }{Speed}\)
= \(\frac{(150+300) }{25}\)
= \(\frac{(450) }{25}\)
= 18 sec
= \(\frac{(150+300) }{25}\)
