1. Using the assembly-line balancing procedure, what is the required workstation cycle time in minutes if the production time in minutes per day is 420 and the required output per day in units is 150? (Keep two decimal points if applicable.)

2.

Task	Task Time (seconds)	Tasks that must Precede
A	30	--
B	16	A
C	19	A
D	20	--
E	20	B,C
F	18	D
G	12	E
H	45	F,G

The above tasks must be performed on an assembly line in the sequence and times specified. The workstation cycle time is 51 seconds. Using the longest task time to balance the assembly line, the first workstation includes , the second workstation includes. , the third workstation includes. , and the fourth workstation includes . (For each blank write tasks in alphabetical order without space or comma. For example, if workstation 1 includes task A, task C and task E, write them as ACE, not A,C,E, A C E or CAE.)
