The video tutorial explains how to calculate the average rate of change of a function using a real-world example. It involves a word problem where a person drives to a friend's house, and the distances at different times are given. The tutorial walks through setting up the problem, calculating the average rate of change using the difference quotient, and interpreting the result as miles per hour.
