Question

Please help me out I have been doing this for hours.

The string distance was 4.75 inches, which represents a real-life distance of about 75 miles. Another group measured the distance between Killeen and Dallas on the same map and found that distance to be 6.25 inches. What is the real-life distance to the nearest mile between Tampa and Orlando?

Answer 1

This is a ratio problem

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. 100 miles is the answer
