Unit Rate: A unit rate is a rate that compares a quantity to one unit of another quantity. For example, if you travel 60 miles in 2 hours, the unit rate would be 30 miles per hour.
Instantaneous Rate: An instantaneous rate measures the rate of change at an exact moment or point in time. It focuses on an infinitesimally small interval and provides information about the rate at that specific instant.
Constant Rate:A constant rate refers to a situation where the change between two quantities remains consistent over time. It means that for every increase or decrease in one variable, there is an equal increase or decrease in another variable.
