A 600-metre-long train is running at the speed of 45 km/h. How much time will the train take to completely cross a stationary pole?
Answer & explanation
Correct answer: option 4
We know ,
Time = \(\frac{Distance}{Speed}\)
Speed = 45 km/h
45 km/h = 45 × \(\frac{5}{18}\) m/sec = \(\frac{25}{2}\) m/sec
Time = \(\frac{600 × 2 }{25 }\)
= 48 seconds
