Question

In​ December, General Motors produced 7 comma 200 customized vans at its plant in Detroit. The labor productivity at this plant is known to have been 0.12 vans per labor hour during that month. 340 laborers were employed at the plant that month.

​a) In the month of December the average number of hours worked per laborer​ = nothing ​hours/laborer ​(round your response to one decimal​ place). ​
b) If productivity can be increased to 0.15 vans per​ hour, the average number of hours worked per laborer​ = nothing ​hours/laborer ​(round your response to one decimal​ place).

Answer 1

a) 176.45

b) 141.2

Step-by-step explanation:

output 7,200

productivity: 0.12 van per labor hour

340 laborer employed

Where:

productivity = outpt/base

0.12 = 7,200/labor hours

7,200 / 0.12 = 60,000 total labor hours

Then we divide by the total laborers to know the average per laborer.

60,000/340 = 176.46 = 176.45 hours

(B) if the productivity increases to 0.15

then:

7,200/0.15 = 48,000

48,000 / 340 = 141.17 = 141.2
