What is the independent and dependent variable in the situation. And what is the rate of change for the situation?
Hannah delivered 12 newspapers after 20 minutes and 36 papers after 60 minutes

not exactly clear, but I'd say that the independent variable is the number of papers. The dependent variable is how long it takes to deliver them.
However, it could also be interpreted as the other way. Given a time period, how many papers can she deliver? 
I think so too. The independent variable is the number of papers and dependent is how long it takes them to deliver.
