A scale on a hiking map shows that 3 inches represents 1.2 miles. What number of inches on the map represent 10 actual miles?

Divide 10 actual miles by 1.2 miles:

10 / 1.2 = 8.333

multiply that by 3 inches:

8.333 x 3 = 25

10 miles would be 25 inches on the map.

Answer: 25 inches on the map represent 10 actual miles.

Step-by-step explanation:

Hi, to answer this question we have to express the information given in ratios:

3 inches represent 1.2 miles = 3/12

x inches represent 10 miles = x/10

Since the ratios are the same

3/1.2 = x/10

Solving for x

(3/1.2) 10 = x

25 inches = x

25 inches on the map represent 10 actual miles.
