The distance remaining for a road trip over several hours is shown in the table. use information to find the constant rate of change in miles per hour.

time (h) distance left (mi)
2 480
4 360
6 240
8 180

-60 miles per hour          

Step-by-step explanation:

We are given the following information in the question:

Distance left:       480     360     240     180

(miles)

          Time:         2         4         6          8

       (hours)

To find the constant rate of change in miles per hour we use the following formula:

Constant rate in miles per hour = , where are the distances in miles and are time in hours.

Putting down values from the given data in the formula, we get:

Here, the negative sign tells us about the inverse relationship that as the time increases the distance is decreasing.

answer: all the values are within because it has a pattern that repeats from -6 to 4.

good luck!
