The correct answer is option 2: About 3300 m.

To calculate the distance of the storm, we can use the formula: distance = speed × time.

The speed of sound in air is 330 m/s, and the time elapsed is 10 s. Therefore, the distance traveled by the sound is 330 m/s × 10 s = 3300 m.

The speed of light in air is 3 × 10^8 m/s, but in this case, we do not need to consider the speed of light since we are given the time elapsed between seeing the lightning flash and hearing the thunder.

So, the distance of the storm is approximately 3300 m.
