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?
Answer & explanation
Correct answer: option 3
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
