In the table below you will find the task involved in a production process where each and every other task is completed based on the completion of the other task. The final step completed is on Task M. Based on the chart, give the answers below:

Task	Time (in minutes)	Task must complete
A	0.5	-
B	1.0	A
C	2.2	B
D	2.3	A
E	0.5	B
F	3.2	D
G	0.5	C
H	0.6	E
I	0.2	E
J	0.2	G
K	1.2	H,J
L	3.2	F,I
M	0.0	K,L
