To find Raul's speed in miles per hour, we use the formula:

\[
\text{Speed} = \frac{\text{Distance}}{\text{Time}}
\]

In this case, the distance is 8 miles and the time is \( \frac{4}{5} \) hours.

Now we can calculate the speed:

\[
\text{Speed} = \frac{8 \text{ miles}}{\frac{4}{5} \text{ hour}} = 8 \times \frac{5}{4}
\]

Calculating the multiplication:

\[
\text{Speed} = \frac{8 \times 5}{4} = \frac{40}{4} = 10 \text{ miles per hour}
\]

To express 10 miles per hour as a fraction, we can write it as \( \frac{10}{1} \). However, if we need to find the closest option in your list, we can convert it to a fraction related to the choices given, but none of the options you provided (1. \( \frac{4}{5}8 \), 2. \( \frac{4}{5} \), 3. \( \frac{8}{5} \), 4. \( 8 \frac{4}{5} \)) directly matches the speed we calculated.

The calculated speed of 10 miles per hour may not directly reflect any of the options you provided. Can you double-check the options?
