How many units can a worker produce per hour according to the provided data?

The correct answer reflects the worker's production rate based on the provided context or data outline. When determining how many units a worker can produce per hour, it's essential to consider factors such as the time taken to produce each unit, the efficiency of the production process, and any time allocated for breaks or other activities.

In this instance, 12.5 units per hour indicates that, when practical efficiency and production time are analyzed, the worker produces half of a unit every four minutes, or an equivalent rate that balances production consistency with potential downtime or slowdowns inherent in any manufacturing process. This value suggests that the worker is operating at a level that allows for sustained output throughout the hour, without overloading the capacity, which might lead to errors or inefficiencies.

Other options, while providing different production rates, suggest outputs that may not align with the realistic capacity given the parameters set in the data.
