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?
To solve this problem, we can use the formula:
distance = speed x time
We know that the speed of sound is approximately 343 meters per second, and we want to find how many kilometers it travels in five seconds.
First, we can convert 343 meters per second to kilometers per second by dividing by 1000:
343 meters per second ÷ 1000 = 0.343 kilometers per second
Now we can use the formula:
distance = speed x time
distance = 0.343 km/s x 5 s
distance = 1.715 km
Therefore, sound travels approximately 1.715 kilometers in five seconds when the temperature is 68°F.
