The workday is 10.5 hours long. The demand for completed product is 900 per day.

The current cycle time to meet the desired output rate is 42 seconds per unit. The number of workstations is 5. The image attached is how the line has been balanced for the current output.

Fill in the blanks and provide an explanation:
Suppose that demand rose from 900 to 950 units per day. Reduce cycle time to ____ seconds, which may require balancing the line.
Suppose that demand rose from 900 to 1150 units per day. Reduce cycle time to ____ seconds, which may require balancing the line.
