How do you find the rate of change?

The rate of change tells us how quickly something changes over time, like how fast a car is going or how tall a plant grows. To find it, you look at two points: where you started and where you ended up. You then measure the change in distance and the change in time. For example, if a car travels 120 miles in 2 hours, you can find its speed by dividing the distance (120 miles) by the time (2 hours), which gives you a rate of change of 60 miles per hour.
