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

### Instruction:
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?

### Inputs:
table_name: table, columns: ['Gun', '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 Time to ft (m) at 25° (seconds) FROM table WHERE Shell (lb) = 12.5 AND Max. height (ft) > 20000.0
