What is the meaning of Rate of Change

The rate of change refers to the speed at which a variable changes over a specific period of time. In mathematics, it is often associated with derivatives in calculus, where it represents the slope of a tangent line to a curve at a certain point. In a broader sense, it can be used to compare any data that is changing over time. For example, if you are driving a car, your speed is the rate at which the distance changes with time. If a business is growing, the rate of change could refer to the increase in sales or customers over time.
