a) Fill in the table with each path and show your work by calculating the time for each path in the table to determine the critical (longest) path(s). Add/delete rows in the table as needed. Path Time b) Fill in the ES & EF times in the table below working from Start to Finish. Then, fill in the LS & LF times working backwards from Finish to Start. After determining the ES, EF, LS, & LF times, calculate the Slack time for each activity using both Slack = LS – ES and Slack = LF – EF. Note: Both calculations must give you the same answers. Activity ES EF LS LF Slack A B E F G H
