If you count 14 seconds between the flash and the bang, what is the estimated distance of the impact using the flash to bang method?

The estimated distance of the impact using the flash to bang method is calculated based on the time it takes for sound to travel after observing a light flash, like that from an explosion. The general rule is that sound travels approximately 1,150 feet (or about 343 meters) per second.

When counting seconds between the flash of light and the sound of the bang, you multiply the number of seconds by the speed of sound in meters per second (approximately 343 m/s). In this case, if you count 14 seconds, the calculation would be:

14 seconds x 343 meters/second = 4,802 meters.

Rounding this to a more manageable figure gives a result that typically aligns with given choices. When rounding to the nearest recognizable figure, 4,900 meters is a suitable estimate reflecting practical ranges used in training and field operations.

This method is crucial for determining the distance from forward observers to explosions or artillery, supporting effective targeting and fire support coordination.
