Put each problem result on a separate sheet in your file.;**book is attached if the problems displayed seem cumbersome.**;3.11 Dave Fletcher (see Problem 3.10) was able to determine;the activity times for constructing his laser scanning;machine. Fletcher would like to determine ES, EF, LS, LF, and;slack for each activity. The total project completion time and;the critical path should also be determined.
