Answer:
1 inch = 0.3 miles
Step-by-step explanation:
We basically want to know how many miles in real life 1 inch on the map represents. We already know that 4 inches on the map corresponds to 1.2 miles in real life, but we need to find what 1 inch on the map corresponds to. Let's make a proportion:
Cross-multiply:
4x = 1.2
Divide by 4 from both sides:
x = 1.2/4 = 0.3
Thus, the scale is 1 inch = 0.3 miles.
Hope this helps!
