Rate of change refers to the speed at which a variable changes over a specific period. It measures how one quantity changes in relation to another, typically expressed as a ratio or a percentage.
For example, suppose a car travels 150 miles in 3 hours. To find the rate of change (speed) in miles per hour, divide the distance traveled (150 miles) by the time taken (3 hours):
Rate of Change = Distance / Time = 150 miles / 3 hours = 50 miles per hour
So, in this case, the rate of change or speed of the car is 50 miles per hour.
