Since we know 4.75 inches equals 75 miles, we can find what small unit of a inch correlates to 75 miles, and then use that data to find the other answer. To do this, we divide 75 miles by 4.75 inches. We get 16 as an estimate (15.789 to 16). Knowing this, we can multiply 16 to 6.25 and get 100 miles. 100miles is the answer
You divide 16 by 2 to get how many tiles that are laid in 1/3 of an hour. Then multiply that by 3 to get how many tiles in one whole hour. The answer should be 24.
