Sara has the fastest rate
First we have to use the formula R*T=D.
For Sara, we have r*1/8=1/2
This means r=4 after you divide 1/2 by 1/8
For Ben, we can use the same formula
We will get r*1/6=1/3
After dividing, we can conclude that Bens rate is 2mph whereas Saras rate is 4mph. This means Sara's faster
