If you drew a line segment from the point when Kiley got in the cab to the point when she reached her grandmother’s house, at what point would the line segment end?

The sentence needs a descriptor of exactly "what" will happen at gurley and marina. in this case, it is the light at the intersection turning green. in this case, the sentence could be rewritten as "the light at the intersection of gurley and montezuma will turn green exactly three seconds after the light at the intersection of gurley and marina."

In mla style, the works cited page provides information about all the sources cited within the paper or document written. it is often place at the end of the work and it generally   contains the complete name of the author, name of the book/article, etc, place and date.
