Answer 1

Question: It takes Boeing 27,400 hours to produce the fifth 787 jet. The learning factor is 75%. Time required for the production of the twelfth 787:

Answer: 19068 hours

Explanation:

Given that:

T5 = 27400 hours

Learning Curve = 75%

Now, from the Learning curve coefficients table

C = 5th of 75% = 0.513

Now:

Let us first find hours required to produce first Boeing:

T1 = 27400 / 0.513

T1 = 53411.3060429

T1 = 53411.31

Now:

Time required for the production of the 12th 787 is given by:

T12 = T1 x C

Here: C = 12th of 75% = 0.357 and T1 = 53411.31

Therefore:

T12 = 53411.31 x 0.357

T12 = 19067.83767

T12 = 19068
