CREATE TABLE table_47912 ("Rider" TEXT, "Manufacturer" TEXT, "Laps" FLOAT, "Time" TEXT, "Grid" FLOAT)

Can you tell me the average Laps that has the Time of +17.485, and the Grid smaller than 7?
SELECT AVG("Laps") FROM table_47912 WHERE "Time" = '+17.485' AND "Grid" < '7'
SELECT AVG("Laps") FROM "table_47912" WHERE "Grid" < '7' AND "Time" = '+17.485'
