**MathMate**, Sunday, October 4, 2009 at 2:51pmLet the plane be H m above the observer.

Time taken for sound to reach observer, t

= H/330 s

Distance plane travelled in time t, D

=H sin(30°) m

Speed of plane

= distance / t

= D/t

= H sin(30°) / (H/330) m/s

= 330 sin(30°) m/s

Convert to km/h if necessary (multiply by 3.6).
