Answer 1

Answer:

If the question bis asking about the length of pole then , it will be solved in this way

we can use unitry method to find it like:

in 13*1/2= 6.5s train covers a distance of 99m

then in 1 sec it will cover s distance of : 99×2/13=15.230m of distance

so distance covered in 9 sec will be : 15.230× 9 = 137.07 m

so length of electric pole is 137.07m
