You're on Space Station Dodecahedron (shaped exactly like a regular dodecahedron), where each vertex is a research node, and the edges are tubes which connect the nodes.
To fix a critical failure in life support systems, you must travel by connecting tubes, visiting each node of the space station exactly once, and then return to your starting node.
Is this possible?
Hint: The vertex graph of a dodecahedron is provided below.

Laurie is standing on the edge of a cliff at a height of \(h\) above Orlando. Laurie runs horizontally away from Orlando at constant speed just as he throws a ball towards her. The ball reaches a height of \(2h,\) and then Laurie catches the ball as it falls.
What is the ratio of Laurie's speed to the ball's horizontal speed?

In each of the cases below, there exists only one solution whereby the sum of \(n\) positive integers equals the product.
If solution(s) exist for \(n=5,\) find the sum of all possible sums (or equivalently, products).
If such a solution does not exist, submit your answer as 0.
