Answer: Option C

Explanation:

Given:

Length of the train = 240m

Time taken to creoss the pole = 24s

Length of the platform = 650 m

Concept Used:

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

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

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