An aeroplane flies along the four sides of a square at the speeds of 100,200,300 and 400km/hr .find the average speed of the plane around the field.

An aeroplane from point A gives an angle of elevation 60^o and after 20 second when aeroplane is moving with the speed 432 km/hr and makes an angle of 30^o . then find the height of the aeroplane in meter

The angle of elevation of an aeroplane from a point P on the ground is 60^(@) . After 12 seconds from the same point P, the angle of elevation of the same plane changes to 30^(@) . If the plane is flying horizontally at a speed of 600sqrt3 km/h, find the height at which the plane is flying.

The angle of elevation of a fighter from point A on the ground is 60^(@) After a flight of 15 seconds the angle of elevation changes to 30^(@). If the jet is fighting at a speed of 720km/hour . Find the constant height at which the jet is flying.

The angle of elevation of an aeroplane from a point on the ground is 60^(@) .After 15 seconds flight ,the elevation changes to 30^(@) .If the aeroplane is flying at a height of 1500sqrt(3) m , find the speed of the plane
