SUMMARY
The discussion centers on calculating the air temperature based on the time it takes for an echo to return from a cliff 250 meters away. The hunter measured an echo return time of 1.5 seconds, leading to a calculated speed of sound of 83.33 m/s. Using the equation v = 331 m/s + (0.59 m/s/°C)T, the temperature can be derived by rearranging the formula to solve for T. The distance traveled by the sound wave is confirmed to be 250 meters, as the echo reflects back to the hunter.
