Writing a paper is not like painting a wall. There have to be agreements about what is to be written, which takes more time. I would not know how to figure this out.

Your question makes about as much sense as this one:
Sara can drive to Chicago in 5 hours, Jasmin can do the same trip in 7 hours. How long will it take the two of them driving together?
