Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE files ( f_id VARCHAR, duration VARCHAR )
TABLE: CREATE TABLE song ( resolution INTEGER, f_id VARCHAR )

### Question ###
What are the maximum and minimum resolution of songs whose duration is 3 minutes?

### Accurate SQL ###

SELECT MAX(T2.resolution), MIN(T2.resolution) FROM files AS T1 JOIN song AS T2 ON T1.f_id = T2.f_id WHERE T1.duration LIKE "3:%"
