Answer:
The rate of change is 3 Inches/minute
Explanation:
Given : The equation D equals 3 T represents the relationship between the distance D in inches that a snail is from a certain Rock and the time T in minutes
To Find : what does the 3 represent
Solution :
D = Distance in Inches
T= Time in minutes
Since the given equation is :

Since it is linear function
Equation of line :

Where m is the slope (rate of change)
Now compare the given equation with equation of line
So, m = 3
Thus 3 is the rate of change per minute
Hence the rate of change is 3 Inches/minute
