Question

To complete the first setup on a new machine took an employee 280 minutes. Using an 75​% cumulative average−time learning curve indicates that the second setup on the new machine is expected to take​ ________.

Answer 1

Answer: 140 minutes

Explanation:

From the question, we are informed that to complete the first setup on a new machine took an employee 280 minutes. Using an 75​% cumulative average−time learning curve indicates that the second setup on the new machine is expected to take​:

We first multiply the 75​% cumulative average−time by the 280 minutes used. This will be:

= 280 × 75%

= 280 × 0.75

= 210

(280 + y)/2 = 210

280 + y = 210 × 2

280 + y = 420

y = 420 - 280

y = 140 minutes
