An assembly line is to operate eight hours per day with a desired output of 200 units per day. The following table contains information on this products task times and precedence relationships:

TASK	TASK TIME (SECONDS)	IMMEDIATE PREDECESSOR
A	60
B	60	A
C	50	A
D	70	A
E	30	B, C
F	110	C, D
G	70	E, F
H	70	G

b. What is the required workstation cycle time to meet the desired output rate? (Round your answer to the nearest whole number.)

Workstation cycle time seconds per unit

c. Balance this line using the longest task time. (Leave no cells blank - be certain to enter "0" wherever required.)
