Final answer:
Labor productivity is 2.5 tires per labor hour.
Step-by-step explanation:
Labor productivity can be defined as the amount of output produced per unit of labor input. In this case, the labor productivity for the production of bicycle tires is 2.5 tires per labor hour. This means that for every hour of labor, the company is able to produce 2.5 tires.
To calculate labor productivity, we divide the total number of tires produced (1,000) by the total number of labor hours (400): 1,000 / 400 = 2.5 tires per labor hour.
