Consider the network shown in the figure. The architect decides to remove a few of the (undirected) arcs but still have each node connected to at least one other node within a single network.
 
  Which arcs should be removed and what is the total arc length that is removed?

Answer: The arcs to be removed are arcs 1-2=13, 2-5=17, 3-6=10, 1-4=15, for a total arc length removed of 13+17+10+15=55 units. The remaining arc length is 40. Not too shabby
