Answer:
4.80 seconds
Explanation:
The velocity of sound is obtained from;
V= 2d/t
Where;
V= velocity of sound = 329.2 ms-1
d= distance from the wall = 790.5 m
t= time = the unknown
t= 2d/V
t= 2 × 790.5/ 329.2
t= 4.80 seconds
The time is taken by the sound to reach the hiker will be t= 4.80 seconds
The sound velocity is defined as the distance traveled by the sound wave in a particular direction with respect to time.
The velocity of sound is given by the formula:
[tex]V=\dfrac{2d}{t}[/tex]
Here;
V= velocity of sound = 329.2 [tex]\frac{m}{s^2}[/tex]
d= distance from the wall = 790.5 m
t= time = the unknown
The time will be calculated as:
[tex]t=\dfrac{2d}{V}[/tex]
[tex]t=\dfrac{2\times 790.5}{329.2}[/tex]
[tex]t=4.80\ seconds[/tex]
Hence the time is taken by the sound to reach the hiker will be t= 4.80 seconds
