    Dear Sir,

    Could you please help?

    A manufacturing company wants to measure the learning rate that it has achieved with the manufacture of a new product item. The first item produced took 6 hours to make and the average time for the first 16 units was 3.3 hours.

    What has been the learning rate for this product to nearest 1?

    Answer
    86%

    3.3/6 r4 =0.55
    r 0.861 therefore 86.1%

    I used the equation
    3.3= 6x(16r4)
    0.557/16
    r4 0.034375 0.43 43%

    Which one is the correct?

    thanks

    Gabriella

    The answer of 86.1% is correct!

    I really do not know what you are doing in your workings.

    This is simply application of the doubling rule.

    The average time per unit to make 16 is the average time to make 1 multiplied by (the learning rate^4)
