Hi there! I can help you! So on the map, Stafford and Princeton is 6 1/4 miles apart. To find the distance from Stafford to Georgetown, add the numbers 3 1/2 and 3 3/4, in order to get 7 1/4. This is because you have to also add the distance from Stafford to Arlington and THEN add the distance from Arlington to Georgetown. Now, let’s subtract the numbers. 7 1/4 - 6 1/4 is 1. There. It is 1 mile farther from Stafford to Georgetown, than from Stafford to Princeton.
