Table schema:
CREATE TABLE table_name_75 (prom__m_ INTEGER, peak VARCHAR, height__m_ VARCHAR, class VARCHAR)

Question: What is the average prom (m) when the height (m) is more than 733, the class is Hewitt, and the peak is Kirk Fell East Top?
SQL: SELECT AVG(prom__m_) FROM table_name_75 WHERE height__m_ > 733 AND class = "hewitt" AND peak = "kirk fell east top"
