To determine the approximate distance between San Antonio and Houston using a graphic map scale, follow these steps:
-
Locate the Cities on the Map: Find San Antonio and Houston on the map you are using.
-
Use a Ruler or a Straight Edge: Place a ruler or straight edge between the two cities.
-
Measure the Distance: Record the measurement in inches (or centimeters).
-
Refer to the Graphic Scale: Look at the graphic scale on the map to see how the measurement translates into real-world distances. For example, if the scale indicates that 1 inch represents 50 miles, you would multiply the measured distance in inches by 50 to find the equivalent distance.
-
Calculate the Distance: Based on your measurement and the map's scale, calculate the approximate distance between San Antonio and Houston.
If you're performing this calculation accurately, most estimates suggest that the distance is around 200 miles between the two cities. If you follow these steps and find a reading on your ruler, you should arrive at an approximate distance that is within 10 miles of that figure.
