The final approach of an aeroplane when landing requires the pilot to adjust their angle of descent to about 3°. If the plane is 12 metres above the runway and has d metres until touchdown, find d to the nearest metre.
Please directly answer the question and provide the final value, e.g., 1, 2.5, 300.
