CREATE TABLE table_48052 ("Rider" CLOB, "Manufacturer" CLOB, "Laps" FLOAT, "Time" CLOB, "Grid" FLOAT)

With a Grid less than 15, and a Time of +52.833, what is the highest number of Laps?
SELECT MAX("Laps") FROM table_48052 WHERE "Grid" < '15' AND "Time" = '+52.833'
SELECT MAX("Laps") FROM "table_48052" WHERE "Grid" < '15' AND "Time" = '+52.833'
