Final answer:
Ronnie's total distance traveled is the sum of the distances of each leg of his journey, 6 miles north and 12 miles south, resulting in a total of 18 miles.
Step-by-step explanation:
To determine Ronnie's total distance traveled, we must add the individual distances from each leg of his journey together. First, Ronnie drives 6 miles north from his house to the store. He then drives 12 miles south, passing his house, to get to the gym. Since distance is a scalar quantity, it only concerns the magnitude and not the direction of travel. Therefore, we add the two distances:
- 6 miles north to the store
- 12 miles south to the gym
Total distance = 6 miles + 12 miles = 18 miles.
The correct answer to Ronnie's total distance traveled is Option C) 18 miles.
