PMCalculating Learning rate

To answer this question can you provide time taken to make the first batch

How you can use r*4 ##The major rule to master is the learning rate comes into play when production is doubled ##The Average time to make a batch unit or whatever is reduced by learning rate when production doubles Therefore this is how production doubles 1st batch 2nd batch 4th batch 8th batch 16th batch You did not mention what the time taken to make first batch was so l will use x Therefore First batch Average time = xhrs/1unit Second Batch Average time =xhrs multiplied by learning rate (r) 4th Batch Average time = xhrs multiplied by learning rate (r)^2(r^2 means r to the power2) 8th Batch Average time = xhrs multiplied by learning rate (r)^3 16th Batch Average time =xhrs multiplied by learning rate (r)^4 From the question total time to make 16 batches is 8500hrs So average time is 8500hrs/16 batches=531.25 Using our formulae of the 16th batch average time is equal to xhrs (r)^4 and we know that our average time for the 16th batch is 531.25 hence we equate the two so xhrs (r)^4 =531.25

assuming that the first batch takes a total of 750 hrs your answer would be : 8500= 16 x 750 r4 : 8500/ (16 x750) = r4 :r= 91.7% or 92% r4 is computed as [4[2ndF] yx] depending on your calculator.
