Question: What is the amount of time (sum) at 40° that it takes a 16 lb shell to reach a maximum of no more than 22,000 ft?
SQL: SELECT COUNT("time_to_ft_m_at_40_seconds") FROM "performance" WHERE "shell_lb"=16 AND "max_height_ft"<'22,000';

Question: What is the average maximum height of a shell that travels for more than 16.3 seconds at 55° and has a maximum velocity of 2200 ft/s?
SQL: SELECT AVG("max_height_ft") FROM "performance" WHERE "time_to_ft_m_at_55_seconds">16.3 AND "m_v_ft_s"=2200;

Question: What is the maximum amount of time a shell travels at 55° when it traveled less than 9.6 seconds at 40°?
SQL: SELECT MAX("time_to_ft_m_at_55_seconds") FROM "performance" WHERE "time_to_ft_m_at_40_seconds"<9.6;

Question: What is the weight of the shell that reached its maximum height at 40° in 12.6 seconds?
SQL: SELECT "shell_lb" FROM "performance" WHERE "time_to_ft_m_at_40_seconds"=12.6;

Question: What is the average maximum height of the shell smaller than 12.5 lb that reached its maximum height at 25° in 10.1 seconds?
SQL: SELECT AVG("max_height_ft") FROM "performance" WHERE "time_to_ft_m_at_25_seconds"='10.1' AND "shell_lb"<12.5;
