The angle of elevation of a jet plane fr...

The angle of elevation of a jet plane from a point A on the ground is `60^(@)`. After a flight of 15 seconds, the angle of elevation changes to `30^(@)`. If the jet plane is flying at a constant height of `1500sqrt3` meter, find the speed of the jet plane. `(sqrt3 = 1.732)`
