An unexpected Journey

Bilbo Baggins lived in a hole in the ground in Vila dos Hobbits. One day, your friend Gandalf, invites you on an adventure. The adventure was based on stealing a dragon's treasure. Bilbo soon thought it would be madness to steal a dragon, but Gandalf had an entourage of dwarves with him to assist him in this toil.

Bilbo then decided to calculate how many days it would take them to reach the Lonely Mountain, where the dragon currently resides. For this calculation it would be necessary to divide the distance in kilometers from Vila dos Hobbits to the Lonely Mountain by the number of people going on the adventure (how did he come up with this metric? I don't know, hobbit things). It is noteworthy that the number of people is the number of dwarfs added to 2 (because Bilbo and Gandalf are also going on the journey).

Bilbo is very busy preparing the two breakfasts for his guests before leaving on the adventure, and then asked you, a very skilled programmer hobbit, to write a program for the calculation requested above. Gandalf provided him with a list with N names that are the dwarves that go on the adventure, and furthermore, the distance X to the Lonely Mountain.
