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? |
42 s 60 s 54 s 48 s |
48 s |
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 |
