The speed of the sound, distance traveled and the time taken relationship is given as follows.
Speed Of Sound= Time Taken/Distance Travelled
From this equation the Distance traveled is derived as
Distance Travelled=Speed Of Sound×Time Taken
That is, Distance Travelled=330m/s×5seconds, given that the speed of sound is 330 m/s.
= 1650 meters.
Hence, the distance of flash from the observer is 1650 meters.
