PLEASE HELP. ILL GIVE YOU A VERY GOOD RATING FOR THE ANSWER!!! ITS AN EMERGGENCY

Answer 1

To find the rate of change we need to use 2 pairs of values. In this case, time will be represented by x and distance will be represented by y, then, the rate of change is found using the following formula:

`m=(y2-y1)/(x2-x1)`

Use 2 pairs of values, for example (4, 260) and (6, 390):

`\begin{gathered} m=(390-260)/(6-4) \\ m=(130)/(2) \\ m=65 \end{gathered}`

The rate of change is 65 miles/hour.

In this case, the rate of change represents the speed.
