Final answer:
The actual distance between Sonja's house and Sal's house, using a scale factor of 1 inch = 12 miles and a map distance of 3 inches, is 36 miles.
Step-by-step explanation:
The question deals with calculating the actual distance on a ground when a scale factor is provided. Assuming the scale factor is 1 inch = 12 miles, and on the map, the distance measures 3 inches, we can simply multiply the scale factor by the map distance to find the actual distance.
Here is the step-by-step calculation:
Identify the scale factor: 1 inch = 12 miles.Measure the distance on the map: Sonja's house is 3 inches away from Sal's house.Calculate the actual distance by multiplying the map distance by the scale factor: 3 inches × 12 miles/inch = 36 miles. Hence, the actual distance between Sonja's house and Sal's house is 36 miles.
