The verb ending is the only thing that changes in present tense form, depending on who does the action. In this case, it is talking about "you" or "tu" meaning that it will end in "-es", or "haces". Therefore the answer would be:
<em>Que haces tu?</em>
<span>500 millas en 10 <span>horas
that is how you say "500 miles in 10 hours" in Spanish
Hope this helped
