Calculate the free float and interfering float for each of the activities shown in the activity network below in Figure 6.17.

Referring to Figure 6.17 above, suppose that the duration for activity F is shortened to 8 weeks. Calculate the end date for the project. Explain your reasoning for this.

What would the end date for the project be if activity F were shortened to 7 weeks? Why?
