Solution: informal
Why? Based on the conversation, we can see that there is a presence of exclamation which is not present in a formal discussion. Therefore this is an informal conversation

New input: Person1: Adam , I'm sorry !
Person2:But where have you been , Alice ? You're over an hour late .
Person1: Yes , but I couldn't help it . I was late getting off work for a start , and then I missed the bus . The bus I did catch got caught in a traffic jam . It was one thing after another .
Person2:But why were you getting off work so late ? The office close at six , doesn't it ?
Person1: Yes , but there's a rush on at the moment , and my boss asked me to do some urgent letters .
Person2:But didn't you tell him you had an appointment ?
Person1: Well , no . I thought I'd finish in about five minutes , and I didn't want to be difficult about just a few minutes . If it hadn't been for missing the bus and the traffic , I wouldn't have been so late . I'm sorry .
Person2:Well , you're here . And that's the main thing .
