Question 3 of 5
Note: Enter your answer and show all the steps that you use to solve this problem in the space provided.
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 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.
To find out how many kilometers sound travels in five seconds, we need to use the following steps:
Step 1: Convert the speed of sound from meters per second to kilometers per second:
1 kilometer = 1000 meters
So, 1 meter per second = 0.001 kilometers per second
Hence, the speed of sound in air is approximately 343 * 0.001 = 0.343 kilometers per second.
Step 2: Calculate the distance traveled by sound in five seconds:
Distance = Speed * Time
Distance = 0.343 kilometers per second * 5 seconds
Distance = 1.715 kilometers
Therefore, sound travels approximately 1.715 kilometers in five seconds
