To determine which option represents the greatest labor productivity, we calculate the productivity for each scenario, which is often measured as the number of units produced per hour of labor.
-
Production of five toy cars in two hours:
- Productivity = 5 cars / 2 hours = 2.5 cars per hour
-
Production of five toy cars in 2.5 labor hours:
- Productivity = 5 cars / 2.5 hours = 2 cars per hour
-
Production of 20 toy cars in four hours:
- Productivity = 20 cars / 4 hours = 5 cars per hour
-
Production of ten toy cars in ten labor hours:
- Productivity = 10 cars / 10 hours = 1 car per hour
Now let's summarize the productivity rates:
- First option: 2.5 cars per hour
- Second option: 2 cars per hour
- Third option: 5 cars per hour
- Fourth option: 1 car per hour
The greatest labor productivity is from the third option: the production of 20 toy cars in four hours (5 cars per hour).
