Explanation:

Step1: Set up unit rate formula

Unit rate = $\frac{\text{Total miles}}{\text{Total days}} = \frac{\frac{1}{2}}{\frac{1}{8}}$

Step2: Divide by multiplying reciprocal

$\frac{1}{2} \times \frac{8}{1}$

Step3: Calculate the product

$\frac{1 \times 8}{2 \times 1} = \frac{8}{2} = 4$

Answer:

4 miles per day
