A man yell's in a long canyon and waits for the echo to come back to him. It takes 3.0 seconds for him to hear the echo of his yell. The sound has to travel down the canyon and back to reach his ears, and sound travels at 343 m/s. How long is the canyon? (Round to the hundredths place - 2 after the decimal)
Well... if it travels 343 meters in one second and it takes 3 seconds to reach him....
each second it goes 343 meters.... and it goes for 3 seconds...
But the canyon is only half that length because it is from the man to the back wall.... so divide your answer in half : )
To find the length of the canyon, we can use the formula:
Distance = Speed × Time
Given:
Speed of sound = 343 m/s
Time taken for the echo to come back = 3.0 seconds
So, using the formula, we have:
Distance = 343 m/s × 3.0 s
Distance = 1029 meters
Therefore, the length of the canyon is 1029 meters.
To find the length of the canyon, we can use the formula:
Distance = Speed × Time
In this case, the speed of sound is given as 343 m/s and the time is 3.0 seconds. Plugging these values into the formula:
Distance = 343 m/s × 3.0 s = 1029 m
Therefore, the length of the canyon is 1029 meters.
