Please help!! A scale on a hiking map shows at 3 inches represents 1.25 miles. What number of inches on the map represents 10 actual miles?

Answer:
24 miles
Step-by-step explanation:
Set up a proportion:
3 inches/1.25 miles = x inches/10 miles
Then cross multiply
30=1.25x
Divide 1.25 on both sides
x=24
