Hassan and Eva rode their bikes from the same starting point. Hassan rode his bike $\frac{5}{6}$ of a mile, while Eva rode hers $\frac{4}{7}$ of a mile. Which equation shows the mileage difference, d, in the distances they rode?

• $\frac{5}{6} + \frac{4}{7} = d$

• $5 - d = \frac{4}{7}$

• $d - \frac{5}{6} = \frac{4}{7}$

• $d + \frac{4}{7} = \frac{5}{6}$
