    【Question】
    Find the average ride duration during the rain of more than 0.8 inches. rain of more than 0.8 inches refers to events = rain where precipitation_inches>0.8; average ride duration = DIVIDE(SUM(duration), COUNT(duration));

    【Evidence】
    rain of more than 0.8 inches refers to events = rain where precipitation_inches>0.8; average ride duration = DIVIDE(SUM(duration), COUNT(duration));

    Please read and understand the database schema carefully, and generate an executable SQL based on the user's question and evidence. 

SQL: SELECT AVG(T1.duration) FROM trip AS T1 INNER JOIN weather AS T2 ON T2.zip_code = T1.zip_code WHERE (T2.events = 'Rain' AND T2.precipitation_inches > 0.8) OR (T2.events = 'rain' AND T2.precipitation_inches > 0.8)
