Answer
# Explanation:
## Step1: Define rate of change
The rate of change of a linear - function representing a real - world situation like calorie - burning is the amount by which the dependent variable (calories burned) changes for each unit change in the independent variable (time in minutes).
## Step2: Identify given rate
We are given that LaToya burned 20 calories per minute. This means for every 1 - minute increase in time on the treadmill, the number of calories burned increases by 20. So the rate of change of the function is 20 calories per minute.
# Answer:
B. 20 calories per minute
