Understanding Rate of Change Concepts

The video tutorial explains how to find the average rate of change using a word problem about a climber's altitude over time. It covers identifying independent and dependent variables, and calculating the rate of change using subtraction and division. The tutorial emphasizes understanding the relationship between time and altitude, and how to apply mathematical operations to solve the problem.
