The speed of sound used in the flash-to-bang method is approximately how many meters per second?

Explanation:
Sound travels through air at roughly 343 meters per second at typical room temperatures, so we round to about 350 m/s for simple calculations. The flash-to-bang method uses distance = speed × time, so each second of delay between seeing the flash and hearing the thunder corresponds to about 350 meters of distance. That’s why the closest value is 350 m/s. The other options would give noticeably different distances for the same time delay (300 would understate, 400 and 450 would overstate).
