Answer:

Here is your answer...

Step-by-step explanation:

Given:

Length of the train= 200m

Length  of the bridge= 125m

Speed of the train= 45kmph or 45000/60*60 m/s = 450/36 m/s


total dist. to be covered by the train to cross the bridge= 200+125= 325m

s=d/t

450/36=325/t

t=325*36 / 450

t= 26 sec.
