Average Rate of Change - Concept

Concept Concept (1)

The average rate of change of a population is the total change divided by the time taken for that change to occur. The average rate of change can be calculated with only the times and populations at the beginning and end of the period. Calculating the average rate of change is similar to calculating the average velocity of an object, but is different from calculating the instantaneous rate of change.
