Second date 35min it's very bad? She had said she had to go to college before lunch?

We scheduled a coffee for the second date but we were together for just over 30 minutes. She had already said before the date that she had to be at college before lunch and therefore it couldn't take long. Don't you think if she was interested she would have made an effort to stay longer?
