Question

Unit times for a job exhibit a learning effect. If the second unit took 30 hours, and the fourth unit took 21 hours, roughly how many hours would you estimate the third unit took?

Answer 1

Answer:

The answer is "24 Hours".

Step-by-step explanation:

The calculated time for $2^{nd}$unit:

$\to T_2 =T_1 \times (2)^{\frac{log(r)}{log(2)}}$

        $=30 ................(a)$

Calculating the time for $4^{th}$unit:

$T_4=T_1\times (4)^{\frac{log(r)}{log(2)}}$

     $=21 ..............(b)$

On dividing the value from equation (a) to (b):

 r= 0.7

Put the value of r into equation (a)  

$T_1=42.8571$

Calculating the value of time for $3^{rd}$ unit:

$= 42.8571 \times (3)^{\frac{log(0.7)}{log(2)}} \\\\=24.35 \ Hours\\\\=24$
