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

  • A. 65 s
  • B. 65 s
  • C. 65 s
  • D. 65 s

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 cross 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
 
:The time taken to cross the platform is 89 s.
