Problems on Trains - Data Intensity 3 :: Discussion


1.What is the speed of the train?
A.I and II only
B.II and III only
C.I and III only
D.III and either I or II only
Answer:  Option  D
Explanation:

Let the speed of the train be x metres/sec.

Time taken to cross a signal pole = Length of the train
Speed of the train
Time taken to cross a platform = (Length of the train + Length of the Platform)
Speed of the train

Length of train = 330 m.

I and III give, 18 = 330     x = 330 m/sec = 55 m/sec.
x 18 3
II and III give, 36 = 2 x 330      x = 660 m/sec = 55 m/sec.
x 36 3

 Correct answer is (D).
