The scale on a map said that 1/2 inch represent 3 miles. if 2 towns are 3 inches apart on the map ,what is the actual distance between the two towns?

  18 miles

Step-by-step explanation:

You can start with the equivalence ...

  1/2 in = 3 miles

and multiply it by 6.

  6·(1/2 in) = 6·(3 miles)

  3 in = 18 miles

Towns that are 3 inches apart on the map are 18 miles apart on the ground.

___

Why 6? because that is the number 1/2 needs to be multiplied by to get 3. Said another way, ...

  3/(1/2) = 3·2 = 6

it would open into a square depending on the type of envelope i’m not sure about the second part
