Answer:
The speed of the sound, distance traveled and the time taken relationship is given as follows.
Speedofsound=
Timetaken
Distancetravelled
From this equation the Distance traveled is derived as
Distancetravelled=Speedofsound×Timetaken
That is, Distancetravelled=330m/s×5seconds, given that the speed of sound is 330 m/s.
= 1650 meters.
