1.Ima New is a recent employee who initially requires 20 minutes to complete a job task. If she experiences an 80% learning rate, how much time will it take her to complete the sixth task

7.78 minutes

Explanation:

Solving Mathematically this will be :

Time for the 6th task = Time for 6 tasks - time for 5 tasks

y = ax^b

where,

y is cumulative time required to produce x units

a is time required to produce first unit of the output

x is the number of units under consideration

b is the log of Learning Curve % divided by 2

therefore,

Time for 6 tasks = 11.23 minutes × 6 tasks

                            = 67.38 minutes

Time for 5 tasks = 11.92 minutes × 5 tasks

                           = 59,60 minutes

Time for the 6th task = 67.38 minutes - 59,60 minutes

                                   = 7.78 minutes

Conclusion :

She need 7.78 minutes to complete the 6th  task

answer; the correct answer to the above statement is (true);
