Final answer:
The takt time, given that 500 units are needed per day and the company operates 2, 8-hour shifts, can be calculated by dividing the total working time in minutes per day (960 minutes) by the demand (500 units), resulting in 1.9 minutes per unit.
Step-by-step explanation:
To calculate the takt time when 500 units are needed per day with the company working 2, 8-hour shifts, we first need to find the total available working time in minutes per day. This will be 2 shifts × 8 hours/shift × 60 minutes/hour, which equals 960 minutes per day. The takt time is the available working time divided by the demand (the number of units needed).
So takt time = total working time/demand
Takt time = 960 minutes / 500 units
Takt time = 1.92 minutes per unit, which can be rounded to 1.9 minutes.
Therefore, the correct answer to the question is b. 1.9 minutes.
