Definition & Meaning of Constant Rate of Change
A constant rate of change refers to a situation where a quantity changes at a consistent, unvarying rate over a specific interval. In mathematical terms, it is often represented in linear equations, where the relationship between two variables can be expressed as a straight line. This concept is crucial in various fields, including economics, physics, and statistics, as it helps in predicting future outcomes based on established patterns.
For example, if a car travels at a constant speed of 60 miles per hour, the distance covered over time can be calculated using the formula: distance = speed × time. This means that for every hour, the car covers 60 miles, demonstrating a constant rate of change in distance with respect to time.
