It would depend on what is changing and on what timescale. For example, the rate of change of speed (acceleration) can be either ms-2 or miles/hour2.

### How do you find the constant rate of change on graph?

You measure the change in the vertical direction (rise) per unit
change in the horizontal direction (run).
The rate of change is constant between A and B if AB is a
straight line.
Take any two points, A = (xa, ya) and B = (xb, yb)
then the average rate of change, between A and B = (yb- ya)/(xb-
xa).

###### Asked in Math and Arithmetic

### What does rate of change mean in math?

A rate of change in a variable Y, if not further qualified, is
the change in Y for a unit change in time.
However, the rate of change may be defined in terms of a unit
change in some other variable (X).
In graphical terms, the rate of change for a straight line is
its gradient whereas for a curve, the rate of change at a point is
the gradient of the tangent to the curve (if a tangent can be
defined).

###### Asked in Science

### What meant by rate of change?

Rate means per unit of time. 5 miles per hour is a rate because
it is expressed as distance per unit of time. Acceleration is a
simple rate of change -- the rate changes. Hmm, maybe I look too
deeply. Perhaps all that is meant is rate. **So rate of change
means rate.** The rate of change of distance is the rate called
speed (or sometimes velocity).
