I think you can probably get a scholarship with a time like that. I think you need 1:51-1:52 for a scholarship. Your Girlfriend has a really really good Running time but I don't think enough to get a scholarship. Her GPA, however, Is a different story.If she got a 34-36 on her Act or a 1400-1600(Not sure about this one I never focused on Sat But..) on her SAT I think she'll get a scholarship. Either Way, I think it's very likely you'll both be able to get in but again I'm not so sure about both scholarships.
I don't believe they have a given set of time qualifiers but rather standards for their recruiting check this link out below located on their athletic page
