Project Duration from Critical Path
MediumCPMcritical path
A project has two complete paths: A-B-C takes 4 + 6 + 3 days, and A-D-C takes 4 + 9 + 3 days. Assuming activities B and D can run in parallel, what is the project duration?
- A13 days
- B14 days
- C16 days
- D22 days
Show solutionHide solution
Answer: C. 16 days
Path A–B–C takes 13 days and path A–D–C takes 16 days. The longest path controls completion, so the critical path is A–D–C and project duration is 16 days.
