To determine how far Ali has walked so far, we subtract the distance remaining from the total distance.

1. Total distance to the campsite: $8 \frac{5}{8} = \frac{69}{8}$ miles.
2. Distance remaining from the campsite: $5 \frac{1}{3} = \frac{16}{3}$ miles.

To subtract these, we first find a common denominator for $\frac{69}{8}$ and $\frac{16}{3}$. The least common denominator is 24.

• Convert $\frac{69}{8}$: $\frac{69}{8} = \frac{207}{24}$,
• Convert $\frac{16}{3}$: $\frac{16}{3} = \frac{128}{24}$.

Now subtract: $\frac{207}{24} - \frac{128}{24} = \frac{79}{24}.$

Simplify $\frac{79}{24}$:

• $\frac{79}{24} = 3 \frac{7}{24}$.

Ali walked $3 \frac{7}{24}$ miles so far.
