While landing at an airport, a pilot made an angle of derpession of `20^(@)`. Average speed of the plane was `200km//h`. The plane reached the ground after 54 seconds. Find the height at which the plane was when it started landing.
`(sin20^(@)=0.342)`

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

Flying to Kampala with a tailwind a plane averaged 158km/h .On the return trip the plane only averaged 112km/h while flying back into the same wind.Find the speed of the wind and the speed of the plane in still air.

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.

An aeroplane flies along the four sides of a square at the speeds of 200, 400, 600 and 800 km/h. Find the average speed of the plane around the field.
