Amanual assembly line must be designed for a product with annual demand of 150,000 units. the line will operate 50 wk/yr, 10 shifts/wk, and 7.5 hr/shift. work units will be attached to a continuously moving conveyor. work content time is 58.0 min. assume line efficiency is 0.95, balancing efficiency is 0.93, and repositioning time is 8 sec. determine the actual number of workers required.

1,407.5 hours

step-by-step explanation:

we first convert all the time to hours and then sum them up.

there are 24 hours in 1 day, in 58 days, there are 24 x 58 = 1,392 hours.

there are 60 minutes in 1 hour, thus, 30 minutes will be equivalent to 30 / 60 = 0.5 hours.

therefore, the number of hours it will take mercury to complete a full rotation is 1,392 + 15 + 0.5 = 1,407.5 hours

can i see a photo of the question so i can you?
