Airport authority has made the regulation that maximum allowable intensity level detected by a microphone situated at the end of 1630 m long runway can be 100 dB. An aeroplane when flying at a height of 200 m produces an intensity level of 100 dB on ground. while taking off, this aeroplane makes an angle of `30^@` with horizontal. Find the maximum distance this aeroplane can cover on the runway, so that the regulation are not violated (assume no reflection).
