A map of an amusement park has a scale of 1½ of an inch to 100 feet. If the actual
perimeter of the amusement park is ½ of a mile, what is the perimeter, in inches, of the
amusement park in the map?
1 mile is equal to 5,280 feet, so 1/2 mile is equal to 2,640 feet.
Using the scale of 1½ inch to 100 feet:
1 inch on the map represents 100 / 1.5 = 66.67 feet
Therefore, the perimeter of the amusement park in the map is 2,640 / 66.67 = 39.6 inches.
So, the perimeter of the amusement park in the map is 39.6 inches.
