Answer

Explanation:

Step1: Identify parallel - start activities

Activities A and B can start simultaneously as they have no predecessors. A takes 2 weeks and B takes 2 weeks.

Step2: Determine subsequent activities

After A is completed (2 weeks), C starts and takes 4 weeks. After B is completed (2 weeks), D starts and takes 5 weeks.

Step3: Analyze further dependencies

After C is completed (2 + 4=6 weeks), E starts and takes 5 weeks. After D is completed (2 + 5 = 7 weeks), F starts and takes 2 weeks.

Step4: Consider the final activity

Activity G can start when both E and F are completed. E will be completed at 6+5 = 11 weeks and F at 7 + 2=9 weeks. So G starts at 11 weeks and takes 2 weeks.

Step5: Calculate the total time

The total time to complete the project is 11+2=13 weeks.

Answer:

13 weeks
