Final answer:
The sound will take approximately 2.34 seconds to reach you if a gun is fired 1/2 mile away.
Step-by-step explanation:
The speed of sound in air is approximately 344 m/s. To calculate the time it takes for the sound to reach you, we need to convert the distance of 1/2 mile to meters. 1 mile is approximately 1609 meters, so 1/2 mile is approximately 804.5 meters. Using the formula distance = speed x time, we can rearrange the formula to solve for time: time = distance / speed. Plugging in the values, we get: time = 804.5 meters / 344 m/s = 2.34 seconds.
