Below is the list of tables from the database along with their columns and datatype. Need to generate an accurate SQL query for the question.
Only use the columns present in the respective table. Only use the columns which are required to generate the SQL query. Only use table joins if required and not otherwise.

### Tables ###
TABLE: CREATE TABLE table_36038 ( "m/v ft/s" real, "Shell (lb)" real, "Time to ft (m) at 25\u00b0 (seconds)" text, "Time to ft (m) at 40\u00b0 (seconds)" real, "Time to ft (m) at 55\u00b0 (seconds)" real, "Max. height (ft)" real )

### 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?

### Accurate SQL ###

SELECT COUNT("Time to ft (m) at 40\u00b0 (seconds)") FROM table_36038 WHERE "Shell (lb)" = '16' AND "Max. height (ft)" < '22,000'
