A map of a town was made using a scale factor of 1 inch =1/2 mile. On the map, Sonja measures that her house is 3 inches away from Sal's house. What is the actual distance between Sonja's house and sal's house?

1.5 miles

Step-by-step explanation:

According to the scale, we can simply multiply the distance that Sonja measured on the map by the actual mile distance that it states on the scale (1/2 or 0.5) to calculate the actual distance between Sonja's house and Sal's house like so...

3 * 0.5 = 1.5 miles

Therefore, we can see now that there is a total actual distance of 1.5 miles between both of their houses, which is represented as 3 inches on the map.
