A scale drawing of a park shows that one inch represents 800 feet. A line segment in the drawing that is 4.75 inches long represents how many feet?
We can just use the ratio set up in the problem. That would be one inch is to 800 feet as 4.75 inches is to X. X is what we are trying to figure out. We can write that ratio as 1/800 = 4.75/X. Right. Now we just need to solve for X. Cross multiplying we get X = 4.75 * 800. That simplifies to X = 3800. So the line segment in the drawing represents 3800 feet.
