### How fast can this family fold 30 pieces of laundry if working together (assuming of course they don't get in each other's way, and can work at the same rate as if working alone) ...

This real-world example problem is useful to know how to do, especially if you have a busy schedule and need to plan ahead. Now, think if the family had 4 kids, how quick could they fold that same load of laundry. I challenge the class (anyone) to work this expanded problem: Data: Mom folds 30 pieces in 15 minutes
