The table below represents atmospheric temperature at a location as a function of the altitude: the average rate of change of the function x = 15 to x = 25 is degree celsius per thousand feet and represent the rate of change of temperature per thousand feet.
answer the blank. correct answer is the

Average rate of change in degree Celsius per thousand feet is -2 °C

Given that;

Average temperature when value of Altitude x is 15 = 4°C

Average temperature when value of Altitude x is 25 = -16°C

Find:

Average rate of change in degree Celsius per thousand feet
