Given:
The temperature of the surrounding is 4 degrees Celsius.
The time taken for the echo to reach the ears is t = 2.8 s
Required:
The distance from the canyon wall.
Explanation:
The distance traveled by the sound is 2d as it travels up to the wall and bounces back.
The distance can be calculated by the formula
[tex]d=\frac{v\times t}{2}[/tex]
Here, the speed of sound at 4 degrees Celsius is
[tex]v=331.3\text{ m/s}[/tex]
On substituting the values, the distance traveled will be
[tex]\begin{gathered} d=\frac{331.3\times2.8}{2} \\ =4.6\times10^2\text{ m} \end{gathered}[/tex]
Final Answer: The distance traveled is 4.6 x 10^2 m
