The Average Rate of Change
Captions available
The idea
The average rate of change of a function between two inputs is the change in output over the change in input — slope on a function.
In practice
A trip's distance reads 30 miles at hour 1 and 150 at hour 3: average rate (150 − 30)/(3 − 1) = 60 miles per hour.
