Question

Question 3 5 pts With a 85% learning curve, if item 25 took 48 minutes to produce, how long would item 50 take to produce (in minutes)? 24.00 40.80 42.50 7.20 5p

Answer 1

Here a 85% learning curve means that the learning rate is 85%.The production has been doubled just once i.e.from 25 to 50.Also,we know that the time taken for the item 25 is 48.

So the required time taken for item 50 =85% of 48=0.85×48=40.80 minutes.

Hence only the 'second option' is correct which has been shown using the calculation.

A 85% learning curve means that the cumulative average time and cost of production would decrease by 15%,each time the production is doubled.Here the production is doubled once.And 15% of 48 is 7.2.So the cumulative average time would decrease by 7.2 minutes and hence next item would take 48-7.2=40.80 minutes.

A learning curve graphically shows the improvement in efficiency of production as more is produced.As per the learning theory,the cost or time taken to produce reduces with the increase in production.A producer learns from the previous production experiences and patterns.The magnitude of improvement in efficiency is determined by the learning rate.
