Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
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?

### 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 AVG Max. height (ft) FROM table WHERE Time to ft (m) at 55° (seconds) > 16.3 AND m/v ft/s = 2200
