A train crosses a 900 metres long platform in 300 seconds. If the length of train is 600 metres. then in how much time does it cross a stationary pole?
Answer & explanation
Correct answer: option 2
Distance = Speed × Time
Speed = \(\frac{DIstance}{Time}\)
Total distance traveled by Train = 900 + 600 = 1500 m
Speed = \(\frac{1500}{300}\) = 5 m/sec
Time required by train to cross a pole ,
length in case of pole = 0
So ,
Speed = \(\frac{600}{5}\) = 120 sec
= 2 minutes
