Use the image to answer the question.
A simple roadmap focuses on the interstate highways connecting Dallas-Fort Worth, Houston, and San Antonio, forming a triangle. Dallas-Fort Worth is at the top center of the map. The road leading from Dallas-Fort Worth to Houston in a southeasterly direction is labeled Route 45. The road leading from Houston to San Antonio in a westerly direction is labeled Route 10. The road leading from San Antonio to Dallas-Fort Worth in a northeasterly direction is labeled Route 35. A scale shows 80 miles and 80 kilometers.
Employ your understanding of the use of a graphic map scale to determine the approximate distance between San Antonio and Houston within 10 miles (you may want to use a ruler).

To determine the approximate distance between San Antonio and Houston, we can use the map scale provided. Using a ruler, we can measure the distance from San Antonio to Houston on the map, and then compare it to the map scale.
Based on the given scale of 80 miles, it looks like the distance between San Antonio and Houston is approximately 2 and a half times the length of the scale.
Therefore, the approximate distance between San Antonio and Houston would be approximately 200 miles.
None of the given answer options match this calculation, so none of the provided responses are correct.
To determine the approximate distance between San Antonio and Houston within 10 miles, we need to use the graphic map scale provided. The scale shows that 80 miles is the length of the distance represented by the line on the map.
Using a ruler or any measurement tool, we can measure the length of the line representing the route from San Antonio to Houston. Let's say the length of this line is 'x' inches.
We need to find the equivalent distance in miles for 'x' inches using the scale.
According to the scale, 80 miles is represented by 'x' inches. Therefore, the scale factor is:
80 miles / 'x' inches
Now, assuming 'y' inches represents the actual distance between San Antonio and Houston, we can set up a proportion:
80 miles / 'x' inches = 80 miles / 'y' inches
To find the value of 'y', we can cross multiply:
80 miles * 'y' inches = 80 miles * 'x' inches
Simplifying the equation, we get:
'x' inches = 'y' inches
This means that for every inch on the map, there is an equivalent mile in reality. Therefore, the approximate distance between San Antonio and Houston is approximately the same as the length of the line on the map, which is 80 miles, according to the scale.
So the correct response is:
approximately 80 miles.
