Show Answer

Answer:

Correct Answer: E

Solution:

Let length of both train and platform be x. Distance covered by the train to cross the platform $ =x+x=2x $ Time = 1 min = 60 s and speed $ 90km/h=90\times \frac{5}{18}=25m/s $

$ \therefore $ $ Distance=Speed\times Time $

$ \Rightarrow $ $ 2x=25\times 60 $

$ \Rightarrow $ $ x=750m $ $ =75000km $
