ACTIVITY $21$: STOPWATCH TIME STUDY CALCULATIONS $2$

Page $1-109-$

objectives: At the end of the activity the students are expected to:

Acquire the skills on setting time standards using stopwatch time study formula.

Utilize cancellation of units to calculate time standards.

Gain the ability to use the time standard formula to solve other unknowns.

Apparatus: Calculators, solution sheets

Problems:

An assembly operator working in the XYZ Company was time studied on a job carrying an allowance factor of $17\%.$

a$.)$ What conversion factor would be used in establishing the standard if the operator is given a performance rating of $0\mathrm{.}90$ or $90\%?$

b$.)$ The standard that was developed allowed $1\mathrm{.}481$ minutes per piece, what would be the money rate per $100$ pieces if a base rate of $$1\mathrm{.}85$ per hour prevailed?

c$.)$ What would be the operator's efficiency if he produced $400$ pieces in an eight $-$ hour day?
