Answer:

The average speed of that car was #55 "length units"/"hour"#.

Explanation:

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

#"Average speed" = "total distance"/"total time"#

#"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 " length units"/"hour"#

I hope this helps,
Steve
