Table schema:
CREATE TABLE table_16439764_1 (m_v_ft_s INTEGER, time_to_ft__m__at_55°__seconds_ VARCHAR)

Question: What is the maximum foot per second speed where time to feet ratio is 22.1 at 55 degrees?
SQL: SELECT MAX(m_v_ft_s) FROM table_16439764_1 WHERE time_to_ft__m__at_55°__seconds_ = "22.1"
