To determine the distance to an impact using the flash to bang method, you can use the standard rule of thumb that for every 5 seconds between seeing the flash and hearing the bang, you are approximately 1 mile away. Since 1 mile is roughly equivalent to 1609 meters, this means that every 5 seconds correlates to about 320 meters.

In the given scenario, if you count 14 seconds, you can break this down into how many 5-second intervals fit into 14 seconds:

  1. Calculate the number of intervals: 14 seconds divided by 5 seconds equals 2.8 intervals.

  2. Each interval corresponds to approximately 320 meters. Therefore, you multiply the number of intervals by the distance per interval: 2.8 intervals × 320 meters/interval.

When you perform that calculation, you get approximately 896 meters. However, since we are determining for the entire 14 seconds, you need to do this in terms of the complete intervals:

  • 2 complete intervals of 5 seconds give you 640 meters (2 x 320).

  • The remaining 4 seconds would add about 256 meters (as each second contributes roughly 64 meters).

Adding these together gives about
