The map scale is 2 inches --> 3 miles
Now you are asked what 6 inches represents. That's *3* times as long on the map, so will be *3* times as long in real life.
6 inches --> 9 miles
It's intuitive and you don't even have to get into thinking about proportions and ratios, etc.
If you want to do it in a more formal, mathematical way:
2/3 = 6/x
Cross multiply:
2x = 18
x = 18/2
x = 9
Answer:
9 miles

you had better leave the planning to someone else.
3 mi/2 in = x mi/6 in
x = 6(3/2) = 9 mi
