Final answer:
Using the map scale where 1 inch represents 5 miles, the distance from Jackson Heights to Jones City is 17.5 miles.
Step-by-step explanation:
To determine how far Jackson Heights is from Jones City, we can use the scale on the map. The scale shows that 1 inch represents 5 miles, so we simply need to multiply the number of inches by the scale factor to find the actual distance. Jim Tree's map measurement of the distance is 3 1/2 inches. Since 1 inch equals 5 miles, you would calculate the distance as follows:
3 1/2 inches × 5 miles/inch = 17 1/2 miles = 17.5 miles.
Therefore, the correct answer to the question, 'how far is Jackson Heights from Jones City?' is D. 17.5 miles.
