Final answer:
To find the number of miles between Irving, TX, and Granbury, TX, we need to convert the given distance of 120 kilometers to miles. By setting up a proportion and solving for the unknown, we find that the measurement closest to the number of miles between the two cities is 75 miles.
Step-by-step explanation:
To find the number of miles between Irving, TX, and Granbury, TX, we need to convert the given distance of 120 kilometers to miles. We know that there are approximately 8 kilometers in 5 miles.
To convert 120 kilometers to miles, we can set up a proportion: 8 kilometers / 5 miles = 120 kilometers / x miles, where x is the number of miles we want to find.
Cross-multiplying, we get 8 kilometers * x miles = 5 miles * 120 kilometers. Simplifying, we have 8x = 600. Dividing both sides by 8, we find that x = 75 miles.
