Suppose the times for the individual operations for the in-line skate assembly are as follows:

Task	Description	Time (sec)
1	Assemble wheels, bearings, and axle hardware	17
2	Assemble brake housing and pad	6
3	Complete wheel assembly	24
4	Inspect wheel assembly	13
5	Assemble boot	22
6	Join boot and wheel subassemblies	11
7	Add line and final assembly	15
8	Perform final inspection	9

Consider the production line achieving an output rate of 150 per hour below. Using the proposed design, calculate the total time and idle time for each workstation. If your answer is zero, enter "0". Round your answers to the nearest whole number.

Station	Tasks	Total Time, seconds	Idle Time, seconds
A	1 and 2
B	3
C	5
D	4 and 6
E	7 and 8
	Total
