Using a standard time of 5 minutes per unit, how many units should a worker produce in an 8-hour shift if 40 minutes of the shift are lost to unavoidable machine breakdown that is not covered in the standard time allowances?
The worker should produce 88 units. The shift has 480 minutes, and after deducting 40 minutes of uncovered breakdown, 440 minutes remain. Dividing 440 by the standard time of 5 minutes per unit gives 88. Ignoring the breakdown would give 96 units.
- A96 units
- B88 unitsCorrect
- C84 units
- D80 units
Explanation
Shift = 480 minutes. Available time = 480 - 40 = 440 minutes. Output = 440 / 5 = 88 units. Check: 88 x 5 = 440. The 96 figure ignores the lost time.
