I can work this out. Your answer is 59 hours. My answer is 78 hours.
1st units takes 25 hours, learning rate is 75% (-0.415)
How long will it take to produce an additional 7 units (to nearest Hour)?
(25 x 7 ^-.415) x7= 78 hours
Please can you explain?
Thanks
StuartMay 19, 2015 at 10:13 am #247109Another one is. Fist units takes 8 hours, and the second take 6 hours, what is the learning rate.
Your answer is 87.5%
Mine is 75% (6hr/8hrs)=0.75 x 100= 75%
How did you get to 87.5% ?
Thanks

For the first question, if they produce an additional 7 units then they will have produced 8 in total. You need to calculate the total time for 8 and then subtract the time for the first in order to get the time for the next 7.
May 19, 2015 at 10:43 am #247117For the second question, the learning rate applies to the average time per unit.
If we make 2, then the average time per unit is (6+8)/2 = 7 hours.
So the learning rate is 7/8 = 87.5%May 19, 2015 at 10:49 am #247120Gotcha 🙂 Thank you
