SUMMARY
The discussion focuses on calculating the distance to a target based on the time it takes for the sound of a bullet striking the target to reach the shooter. The bullet's muzzle speed is 170 m/s, and the sound speed, calculated using the formula Vc=331+(0.6*T) with a temperature of 72°F (22.2°C), is 344.32 m/s. The total time from firing to hearing the impact is 1.30 seconds. The equation 170x + 344.32(1.3 - x) = D is established to find the distance to the target, where x represents the time taken by the bullet to reach the target.
