Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.

The train covers 100m and it's own length - t.
D = S*T
= 12.5 m/s * 60 s
= 750 m

100+t = 750
t = 650.

Time taken to cross electric pole is T = D/S
650(consider pole to be a line) / 12.5
= 52 sec
