A company is intending to produce a new product.
They have made two ‘test’ units – the first of them took 8 hours to make, and the second took 6 hours.
The learning rate is 87.5% and I am getting 75%.
How to prove it to be 87.5%.The average time per unit, if they make 2 units, is (8+6)/2 = 7 units.
Therefore the learning rate is 7/8 which is 87.5%. The learning rule applies to the average time per unit.
I do suggest that you watch the free lecture on this because I go through an almost identical example!!

Please how can I use my calculator to compute learning rate. For example, the learning rate in Dec 2014 was 70% (r3). How can arrive @ that using a Casio calculator?
You cannot be asked to calculate the learning rate using the formula.
When it is asked you are expected to calculate it using the doubling rule.
Lectures have been uploaded showing the workings for all of the questions in the December 2014 exam, and you can see how to calculate it there (you need to use the cubed root button on your calculator – you do not say which Casio calculator you have, but if it is a scientific calculator (and you must have a scientific calculator for the exam) then you should have no problem taking a cubed root.
