Final answer:
An example of a real-world situation with an additive relationship between two quantities is the distance traveled by a car and the time it takes. The equation that models this relationship is Distance = Time x Speed.
Step-by-step explanation:
An example of a real-world situation with an additive relationship between two quantities is the distance traveled by a car and the time it takes. Let's say that the car travels at a constant speed of 60 miles per hour. We can create a table with three pairs of values:
Time (hours), Distance (miles)
1 60,
2 120,
3 180
In this case, the equation that models the relationship between the time and distance is Distance = Time x Speed. Since the car travels at a constant speed of 60 miles per hour, the equation can be simplified to Distance = 60 x Time.
