1. A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?

  • A. 80. Sec
  • B. 80. Sec
  • C. 80. Sec
  • D. 80. Sec

Answer: Option B

Explanation:

Given:

Length of the train = 240 m 

Time taken to cross the pole = 24 s 

Length of the platform = 650 m

Concept Used:

Time take into the platform = (length of train + length of the platform)/speed of the train

Speed of train = length of train/time taken

Calculation:

Speed of train = 240/24 = 10 m/s

Time taken to cross the platform = (240 + 650)/10 = 890/10= 89 s.
