Dave Fletcher 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. Here are the activity times: Activity Time (weeks) Immediate Predecessor(s) | Activity Time (weeks) Immediate Predecessor(s) 6 4 B B - W O 11 C, E DD 6 D , F Dave's earliest start (ES) and earliest finish (EF) are: Activity ES EF A 6Ross Hopkins, president of Hopkins Hospitality, has developed the tasks, durations, and predecessor relationships in the following table for building new motels. :1 Time (weeks) Immediate Time (weeks) Immediate Activity a m b Predecessor(s) Activity 3 m b Predecessor(s) A 6 9 10 G 2 3 4 C, E B 1 8 23 A H 2 2 2 F C 8 14 18 A | 7 7 7 F D 5 6 9 A J 6 7 14 D, G, H E 1 2 4 B K 3 3 4 I, J F 5 8 20 C, E a) The expected (estimated) time for activity C is weeks. {Round your response to two decimal places.)
