The angle of elevation of an airplane from a point A on the ground is \( 60^{\circ} \). After a flight of 15 seconds, the angle of elevation changes to \( 30^{\circ} \). If the airplane is flying at a constant height of \( 1500 \sqrt{3} \mathrm{~m} \), the speed of the airplane ishttps://bit.ly/YTAI_PWAP https://www.pw.live
