Final answer:
To center her car in the garage, the woman should park it so that the front wheels are 2 feet from the front of the garage.
Step-by-step explanation:
To calculate how far the front wheels of the car need to be from the front of the garage in order to center a 15-foot long car in a 19-foot long garage, we first find the available space by subtracting the length of the car from the length of the garage (19 feet - 15 feet = 4 feet). This available space of 4 feet will be distributed evenly on both the front and back of the car when it's centered. Therefore, we divide the available space by 2 to find the distance for each side (4 feet ÷ 2 = 2 feet). So, the front wheels should be 2 feet from the front of the garage for the car to be centered.
