The average speed of that car was $55 \text{length units"/"hour}$.

#### Explanation:

The total distance was 300.0 length units. The total time was 5.5 hours.

$\text{Average speed" = "total distance"/"total time}$

$\text{Average speed" = (300.0 " length units")/(5.5 "hours") = 54.54 " length units"/"hour}$

Since the time data has just 2 significant digits, the result should be adjusted to $55 \text{ length units"/"hour}$

I hope this helps,
Steve
