- For one activity the precedences in the two projects are different. State which activity and describe the difference.
- The table below shows the durations of the five activities.
| Activity | A | B | C | D | E |
| Duration | 2 | 1 | \(x\) | 3 | 2 |
Give the total time for project 1 for all possible values of \(x\).
Give the total time for project 2 for all possible values of \(x\).
