Question: How many feet per second does a shell move where the height range is 23500?
SQL: SELECT MIN("m_v_ft_s") FROM gun_performance WHERE "max_height_ft" = 23500

Question: If the gun used is the qf 12 pdr 12 cwt, what is the shell weight?
SQL: SELECT "shell_lb" FROM gun_performance WHERE "gun" = 'QF 12 pdr 12 cwt'

Question: Where the height range is higher than 20000.0 and the shell weight is 12.5, what is the time to feet ratio at 25 degrees?
SQL: SELECT "time_to_ft_m_at_25_seconds" FROM gun_performance WHERE "shell_lb" = '12.5' AND "max_height_ft" > 20000.0

Question: What gun has a time to feet ratio of 18.8 at 55 degrees?
SQL: SELECT "gun" FROM gun_performance WHERE "time_to_ft_m_at_55_seconds" = '18.8'

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 gun_performance WHERE "time_to_ft_m_at_55_seconds" = '22.1'

Question: What is the foot per second speed where time to feet ratio is 9.2 at 25 degrees?
SQL: SELECT "m_v_ft_s" FROM gun_performance WHERE "time_to_ft_m_at_25_seconds" = '9.2'
