We know that the speed of sound is 343 meters per second. Therefore in 1 second, sound would travel 343 meters.
Now we need to find out how many kilometers does sound travel in 5 seconds.
We can start by finding out how many meters sound travels in 5 seconds:
343 meters per second multiplied by 5 seconds = 1715 meters
To convert meters to kilometers, we divide by 1000 (since there are 1000 meters in 1 kilometer):
1715 meters ÷ 1000 = 1.715 kilometers (rounded to three decimal places)
Therefore, sound would travel approximately 1.715 kilometers in five seconds when the temperature is 68°F.
