An observer watching a fireworks display sees the light from the explosion and hears the sound 2 seconds later.How far was the explosion from the observer?

if speed o sound = V meters per second

then 2 V

be answered

To determine the distance of the explosion from the observer, we can use the fact that sound travels at a constant speed in air. The speed of sound in air is approximately 343 meters per second at room temperature.

Since the observer hears the sound 2 seconds after seeing the light, we can calculate the distance using the formula:

Distance = Speed × Time

In this case, the time is 2 seconds, and the speed is the speed of sound in air (343 meters/second).

Distance = 343 meters/second × 2 seconds
Distance = 686 meters

Therefore, the explosion was approximately 686 meters away from the observer.
