The different paths from node 1 to node 11 and their corresponding times are as follows:
Path 1: 1-2-3-5-6-7-11. 
Time: 6+4+2+3+2+4 = 21 weeks.
Path 2: 1-2-3-5-6-8-11.  
Time: 6+4+2+3+4+1 = 20 weeks.
Path 3: 1-2-6-8-11.
Time: 6+6+4+1 = 17 weeks.
Path 4: 1-2-4-9-10-11.
Time: 6+3+4+1+4 = 18 weeks.
Path 5: 1-2-6-7-11.
