WHEN THE TEMPERATURE IS 68 F, THE SPEED OF SOUND IN AIR IS APPROXIMATELY 343 METERS PER SECOND.
APPROXIMATELY HOW MANY KILOMETERS DOES SOUND TRAVEL IN FIVE SECONDS?
We can use the formula d = st, where d is the distance, s is the speed, and t is the time.
First, we need to convert 68 F to Celsius, since the speed of sound formula uses Celsius. The formula to convert F to C is C = (F - 32) x 5/9.
C = (68 - 32) x 5/9 = 20 Celsius
Now we can plug in the values:
d = (343 meters/second) x (5 seconds)
d = 1715 meters
To convert meters to kilometers, we divide by 1000:
d = 1715/1000 = 1.715 kilometers
Therefore, sound travels approximately 1.715 kilometers in five seconds when the temperature is 68 F.
