Answer to **Puzzle 182**: There are infinitely many paths from \\(E\\) to \\(a\\), with costs of the form 9+0.4+n*(2+0.4) for \\(n\in\mathbb{N}\\), \\(\Phi(E,a)\\) should be the infimum of of the possible costs, so \\(\Phi(E,a)=9.4\\).

Similarly,

Answer to **Puzzle 183**: \\(\Phi(W,c)=5.7\\)

Answer to **Puzzle 184**: \\(\Phi(E,c)=9.4\\).
