If you count 11 seconds from the flash to the bang using the flash to bang method, what is the estimated distance?

The flash to bang method is a technique used to estimate the distance of a projectile or explosion by measuring the time interval between seeing the flash (the light from the explosion) and hearing the sound (the bang). Sound travels at approximately 343 meters per second (in air at 20 degrees Celsius), which can be rounded to about 350 meters per second for quick calculations.

To find the distance, you can use the formula:

Distance = Time (in seconds) × Speed of Sound (in meters per second).

In this case, if you counted 11 seconds from the flash to the bang, you can calculate the distance as follows:

Distance = 11 seconds × 343 meters/second = 3,773 meters.

Given the available options, 3850 meters is the closest estimate and typically aligns with the rounding applied in practical situations. This is why the choice of 3850 meters is the most reasonable estimate of the distance based on a flash to bang of 11 seconds. Other options, while numerical possibilities, do not align closely with the calculation based on the typical speed of sound.
