From the image, the question is asking for the rate of change in waiting time between February and March, based on a table provided by the Department of Motor Vehicles (DMV).

Table Values:

• February: 15 minutes
• March: 15 minutes

To find the rate of change:

The formula for rate of change between two values is:

$\text{Rate of Change} = \frac{\text{Change in Value}}{\text{Change in Time}}$

Here:

• Change in Value = March waiting time - February waiting time = $15 - 15 = 0$
• Change in Time = 1 month (from February to March)

Thus, the rate of change is: $\frac{0}{1} = 0 \text{ minutes per month}$

The rate of change between February and March is 0 minutes per month.

Would you like more details or have any further questions? Here are 5 related questions to deepen your understanding:

1. What is the rate of change from March to April?
2. How do you calculate the rate of change between April and May?
3. Why is the rate of change between February and March zero?
4. How would a negative rate of change be interpreted in this context?
5. What is the overall rate of change from February to June?

Tip: A zero rate of change means that there was no difference in values between the two points you're comparing.
