Final answer:
The possible distances between the sink and refrigerator in a kitchen work triangle should be between 4 ft and 9 ft. When creating a scaled diagram, the distance is calculated by multiplying the actual distance by the scale factor. In the case of Anna's room to the kitchen, the distance on the diagram would be 10 centimeters.
Step-by-step explanation:
The kitchen work triangle principle is based on the idea that the primary tasks in a kitchen are carried out between the stove, sink, and refrigerator, and that these should be laid out in a triangle to minimize walking distance and maximize efficiency. A typical guideline for the distance between any two of these fixtures is that it should be no less than 4 feet and no more than 9 feet. Thus, the possible distances between the sink and refrigerator are between 4 ft and 9 ft, making option B the correct answer.
To calculate distances on a scaled diagram, like for Anna's room to the kitchen in her house at a scale of 1/150, you would multiply the real distance by the scale factor. The distance on the diagram from Anna's room to the kitchen would be 15 meters multiplied by 1/150, which equals 0.1 meters or 10 centimeters on the diagram.
