Question: Please write down the trip IDs which ended on the days when the minimum temperature is less than 45 degrees Fahrenheit.
Evidence: the minimum temperature is less than 45 degrees Fahrenheit refers to min_temperature_f<45;

SQL:
SELECT T1.id FROM trip AS T1 INNER JOIN weather AS T2 ON T2.zip_code = T1.zip_code WHERE T2.min_temperature_f < 45
