Question

Girish Shambu and William Reisel are teammates at a discount? store; their new job is assembling bicycles for customers. Assembly of a bike has a learning rate of 80?%. They forgot to time their effort on the first? bike, but spent 6 hours on the second. They have 6 more bikes to do. Determine approximately how much time will be? (was) required? for:

c) The total amount of hours to build the 8 units? =

hours? (round your response to two decimal? places).

Answer 1

Given t2 = 6 hrs---- A

Learning rate = 0.8

b= Log learning rate / Log 2 = log 0.8 / log 2 = -0.322

t2= t1 (n)^b =t1(2)^(-0.322)

Putting in A:

t1(2^-0.322) = 6

0.799 t1=6

So, t1 = 6/0.799 = 7.5 hrs

Unit	Unit Time	Cumulative Time
t1	7.5	7.5
t2	6	13.5
t3	5.265	18.765
t4	4.8	23.565
t5	4.46	28.025
t6	4.2	32.225
t7	4.005	36.23
t8	3.84	40.07

Total amount of hours to build 8 units = 40.07 hours
