job was timed for 60 cycles and had an average of 1.6 minutes per piece.

The performance rating was 97 percent, and workday allowances are 17 percent.

Determine each of the following:

a.

Observed time. (Round your answer to 1 decimal place.)

  Observed time

minutes

b.

Normal time. (Round your answer to 2 decimal places.)

  Normal time

minutes

c.

Standard time. (Round your answer to 2 decimal places.)

  Standard time

minutes

Solution

observed time=1.6/60=0.026 min

Normal time=average element time x performance rating/100

                       =1.6x97/100

                        =1.55min

standerd time=normal time/1-allowence fraction

                          =1.55/1-17%

                           =1.87min
