B 6 A E 10   B H 6 D
C 3 A F 10 C I 2 G, H

b) The activities on the critical path are A-B-E-G-I

Activity Duration, D Early start, ES=Max of early finish of preceding activities Early finish, EF = ES + D Late finish, LF= Min of LS of successor activities Late start, LS= LF - D Total slack= LF-EF Critical activity, activities with 0 slack time
A 10 0 10 10 0 0 Yes
