Networks, SMB-001

The network diagram below describes a skateboard park with seven ramps.

The ramps are shown as vertices , , , , , and on the graph below.
 

The tracks between ramps and and between ramps and are rough, and cannot be used by skateboards.

1. Describe a path that a skateboarder at ramp could use to travel to ramp that uses 4 edges only.   (1 mark)
   

   --- 1 WORK AREA LINES (style=lined) ---

2. A skateboarder begins skating at ramp and follows an Eulerian trail.
3. What trail does the skateboarder take?  (2 marks)
   

   --- 4 WORK AREA LINES (style=lined) ---
