So i'm not sure what they mean by simplest fraction, but i used 20miles/(1/3h)=480mi/8h for Anna's rate and, and 246miles/16h=123mi/8h for Julie's rate 

(since that seemed more simplified than fractions over fractions, didn't involve decimals, and had the same denominator).

From there i saw that Julie's rate was slower and subtracted her rate, from Anna's rate:

480mi/8h - 123/8h = 357mi/8h 

so Julie ride 357mi/8h slower than Anna, (which is about 44.6miles/h when you divide).
