Translation:The girls go to the village by bus.
There are two basic errors here.
The use of the apostrophe with girl's is not correct because that means "of the girls" it's the possessive...for example "The girl's cat is gray." "the cat that belongs to the girl". Here all we need is the plural "the girls".
And then you'll notice that we don't use "the bus" it's a general statement so doesn't use it.
