CREATE TABLE table_20822 ("Gun" TEXT, "m/v ft/s" FLOAT, "Shell  ( lb ) " TEXT, "Time to ft  ( m )  at 25\\u00b0  ( seconds ) " TEXT, "Time to ft  ( m )  at 40\\u00b0  ( seconds ) " TEXT, "Time to ft  ( m )  at 55\\u00b0  ( seconds ) " TEXT, "Max. height  ( ft ) " FLOAT)

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?
SELECT "Time to ft (m) at 25\u00b0 (seconds)" FROM table_20822 WHERE "Shell (lb)" = '12.5' AND "Max. height (ft)" > '20000.0'
SELECT "Time to ft (m) at 25\u00b0 (seconds)" FROM "table_20822" WHERE "Max. height (ft)" > '20000.0' AND "Shell (lb)" = '12.5'
