Line Balancing and Rockness Recycling

Rockness Recycling refurbishes rundown business students. The process uses a moving belt, which carries each student through the five steps of the process in sequence. The five steps are as follows:

STEP DESCRIPTION TIME REQUIRED PER STUDENT
1 Unpack and place on belt 1.0 minute
2 Strip off bad habits 1.5 minutes
3 Scrub and clean mind 0.8 minute
4 Insert modern methods 1.0 minute
5 Polish and pack 1.2 minutes
