To determine the greatest labor productivity, we can calculate the number of toy cars produced per labor hour for each option.
-
Production of 20 toy cars in four hours:
-
Production of five toy cars in 2.5 labor hours:
-
Production of ten toy cars in ten labor hours:
-
Production of five toy cars in two hours:
Now comparing the labor productivity:
- First option: 5 cars per hour
- Second option: 2 cars per hour
- Third option: 1 car per hour
- Fourth option: 2.5 cars per hour
Thus, the option that represents the greatest labor productivity is the production of 20 toy cars in four hours (5 cars per hour).
