Answer:
x = 19.2 miles
Step-by-step explanation:
So the scale says that for every 4 inches on the map, it is 25 inches in real life. Since they are the same units, they can cancel out, giving us 4/25.
We are looking for the mapped equivalence to 120 miles, which gives us the equation 4/25 = x/120 mi.
Cross-multiply: 480 mi = 25x
Divide: x = 96/5 = 19.2 miles
