Miles joined the group tour at the sagada in the middle of the cave she hollers loudly. After 1.22 seconds she hears an echo if the air temperature at the cave is 20 degrees Celsius how far away are the cave walls from miles
To determine the distance between Miles and the cave walls, we need to calculate the time it took for the sound to travel from Miles to the wall and back as an echo.
The speed of sound in air at 20 degrees Celsius is approximately 343 meters per second.
Since Miles heard the echo after 1.22 seconds, it means the sound traveled to the cave wall and back in 1.22 seconds.
To calculate the distance, we use the formula: Distance = Speed × Time.
Distance = (343 m/s) × (1.22 seconds) = 418.46 meters.
Therefore, the distance between Miles and the cave walls is approximately 418.46 meters.
what is the speed of sound in 20° air? If it is v mi/s, then since distance = speed * time, the distance d to the walls is
2d = 1.22v
2d because her yell makes a round trip to the wall and back
