Answer:
6.25 inches
Step-by-step explanation:
3/4 inches = 0.75 inches
If 0.75 inches is the map's scale for 3 miles, then:
0.75 inches / 3 miles = 0.25 inches per 1 mile
Multiply 0.25 inches inches per mile * 25 miles:
0.25 * 25 = 6.25 inches
OR:
0.75/3 = x/25
Multiply 25 by both sides:
x = (0.75/3)*25
x = 6.25 inches
