### Instruction:
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?

### Inputs:
table_name: table, columns: ['m/v ft/s', 'Shell (lb)', 'Time to ft (m) at 25° (seconds)', 'Time to ft (m) at 40° (seconds)', 'Time to ft (m) at 55° (seconds)', 'Max. height (ft)']

### Response:
SELECT COUNT Time to ft (m) at 40° (seconds) FROM table WHERE Shell (lb) = 16 AND Max. height (ft) < 22,000
