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	16
2	Assemble brake housing and pad	8
3	Complete wheel assembly	22
4	Inspect wheel assembly	12
5	Assemble boot	24
6	Join boot and wheel subassemblies	10
7	Add line and final assembly	12
8	Perform final inspection	12

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

What is the assembly line efficiency? Round your answer to one decimal place.
