# Visiting a friend

Geometry Level 2

In a special 4-dimensional city, every point in space is represented by a set of four numbers ( i.e. $$(4,2,2,1)$$ ). The numbers form the coordinates of a given point. The distance between any two adjacent points is 1 unit. Jordan wants to get from his house at $$(2,2,2,2)$$ to his friend Nadroj's house at $$(10,10,10,10)$$. What is the distance in points that Jordan has to travel?
