Answer:

128 ft/s; it represents the average speed of the object between 2 seconds and 6 seconds

Explanation:

The average rate of change is another way to say slope.

slope = (y2-y1)/(x2-x1)

= (576-64)/(6-2)

= (512/4)

=128 ft/s


This represents the change in ft per second, or the average speed the object is going during the time period.
