anonymous · Answer

The distance you travel is equal to your velocity times time:
$$d=vt=59 mph \times 5.5 hours = 324.5 miles \approx 325 miles$$

mathstudent55 · Answer

average speed = distance / time
distance = (average speed) * time

anonymous · Answer

The algebraic methods above are both correct.  Also consider the approximation method.  $$5.5 hours*60-5.5=330-5.5=324.5 \approx 325$$This method lets you get the answer in your head, without pencil/paper/calculator.  Mental math is useful out there in real life....
