Question

The number of pedestrian fatalities in the United States declined approximately steadily from 4,795 fatalities in 2006 to 4165 fatalities in 2009.

Find the “average rate of change” of the number of pedestrian fatalities.

Answer 1

Average rate of change = 0.1313 or 13.13% (approx.)

Explanation:

Given:

Pedestrian fatalities in 2006 = 4,795

Pedestrian fatalities in 2009 = 4,165

Find:

Average rate of change

Computation:

Average rate of change = [4,165-4,795] / 4,795

Average rate of change = [-630] / 4,795

Average rate of change = 0.1313 or 13.13% (approx.)
