To determine the approximate distance between San Antonio and Houston using a graphic map scale, follow these steps:

1. Look for the graphic scale on the map. It is usually a line with markings indicating distance.
2. Measure the distance between San Antonio and Houston on the map using a ruler. Let's say it measures 2 inches.
3. Locate the corresponding unit of distance on the graphic scale. For example, the scale might indicate that every inch on the map represents 100 miles.
4. Multiply the measured distance (2 inches) by the corresponding unit of distance (100 miles/inch). In this case, it would be 2 inches * 100 miles/inch = 200 miles.
5. Estimate the distance within 10 miles by adding or subtracting 10 miles from the calculated distance. So, the approximate distance between San Antonio and Houston would be around 200 miles +/- 10 miles.

Therefore, the closest response option would be "approximately 240 miles".
