A 480 m long train takes 16 seconds to pass a pole. How long will it take to pass a platform that is 900 m long?

46 seconds

Distance = Speed × Time

Speed = \(\frac{DIstance}{Time}\)

Speed of train = \(\frac{480}{16}\) = 30 m/sec

Time require to cover 900 m long platform = \(\frac{480 + 900}{30}\)

= \(\frac{1380}{30}\)

= 46 seconds
