47                       32.52  

50                       33.5                                            0.34

56                       35.50                                   0.33

60                       36.74                                   0.31

62                       37.35                                          0.305

65                       38.24                                   0.3

In the context of this problem, the average rate of change is the rate at which the car decelerates as it skids. As the distance that the car skids increases, the rate at which the car decelerates decreases at a gradual rate.

A map of the United States has a scale of 1 inches = 300 miles. The distance on the map from Boise, Idaho, to Phoenix, Arizona,
Nostrana [21]

Answer:

The distance is 750 miles.

Step-by-step explanation:

In order to find this, we create a proportion. On the left would be the scale factor. On the right would be the Idaho to Arizona distance.

1in / 300 mi = 2.5in / x mi

Now we can cross multiply to find the distance.

300 * 2.5 = 1 * x

750 mi = x
