space voyage World problem
Sorry if I am in the wrong place, just let me know!
Thanks in advance for any help.
A space crew is ready to partake on a voyage across the galaxy. While preparing for their voyage, the captain explains the situation they are about to encounter. He states that they have an unlimited supply of rocket fuel available where they are. they want to travel 800 light years through space, but there is no available rocket fuel along the way. Your crew has one rocket and you need to voyage across the galaxy. Your rocket can carry 500 light years (consider this "one load"), and you can build up refueling stations at any spot along the way. These caches may be any size and it is assumed that there is no evaporation loss. the crew only need to make is 800 light years through space, and they do not have to worry about making it back to their docking station. Assume the crew is working on a horizontal plane. There is no time limit.

A. What is the minimum amount of rocket fuel (in LOADS) the rocket will require crossing the galaxy? Show all work, explain your answer in a paragraph and include a drawing.

B. is there a limit to the width of the galaxy the rocket can cross? Why or why not, explain?

Thanks again if you take the time to read this. I have been trying for days to solve this and have only gotten so far. (Yes, this is for a college Engineering class if anyone was wondering)

Sincerely,
Joey D

If it's "for a college Engineering class", then it's likely for a grade. Forum policy is not knowingly to help with problems that count towards a grade.

I'm sorry, I should have clarified. It is a practice problem. It is not being graded. We just started the semester.
