Int float = T.F.-F.F.

Activity	Immediate Predecessor	Duration (days)	EST	EFT	LST	LFT	TF	FF	Ind F	Int F
A	-	3	0	3	0	3	0	0	0	0
B	A	5	3	8	5	10	2	0	0	2
C	A	7	3	10	3	10	0	0	0	0
D	A	9	3	12	14	23	11	0	0	0
E	B, C	11	10	21	10	21	0	0	0	0
F	D	5	12	17	23	28	11	0	-11	11
G	F	6	17	23	28	34	11	11	0	11
H	-	8	0	8	26	34	26	26	26	26
I	E	13	21	34	21	34	0	0	0	0
J	G, H, I	16	34	50	34	50	0	0	0	0

Critical path = 10-20-50-60-80-90

Critical activity = A-C-E-I-J

Project duration = 50 days
