Introduction: Measuring Steady Change and Overall Speed
Have you ever watched a candle burn down, millimeter by millimeter, at a predictable pace? That steady, unchanging rate is an example of a constant rate. Now, imagine a bumblebee darting from flower to flower—sometimes fast, sometimes slow, sometimes hovering. The overall speed of its entire journey is an average rate.
Understanding the difference between constant and average rates is essential for solving many real-world math problems, from calculating fuel efficiency to determining travel times. This lesson will teach you how to identify, calculate, and apply both types of rates.
What Is a Constant Rate?
A constant rate is a rate that remains steady and unchanging over time. When something moves or changes at a constant rate, the relationship between the quantity and time is linear and predictable.
