There's no single answer to the distance between Texas A&M University and Blinn College because both are multi-campus institutions. Texas A&M's main campus is in College Station, but Blinn has multiple campuses across the Brazos Valley region, including one in Bryan (very close to College Station) and others further afield.
To get an accurate distance, you need to specify which Texas A&M campus (likely College Station) and which Blinn College campus you're interested in. Then you can use a mapping service like Google Maps to find the distance.
