Question Analysis
This question tests the student's understanding of the concept of constant rate of change and its application in a real-world scenario. The problem provides a specific example of a car traveling a certain distance over a given time, and the student must calculate the speed.

Key Concept Explanation
The constant rate of change is a fundamental concept in linear relationships. It represents the consistent ratio of change in one variable relative to another. In this case, the rate of change is the speed of the car, which is calculated by dividing the total distance traveled by the total time taken.

Step-by-step Solution
1. Identify the given values: distance = 120 miles, time = 3 hours.
2. Use the formula for the constant rate of change:
