To estimate the distance you are from a lightning strike, you can count the number of seconds between seeing the flash and hearing the associated thunderclap. for this purpose, you can consider the speed of light to be infinite (it arrives instantly). sound travels at about 343 m/s in air at typical surface conditions. how many kilometers away is a lightning strike for every second you count between the flash and the thunder?

Ans. For every second you count between the flash and the thunder you should count 0.343 Kilometers.

Step-by-step explanation:

Hi, this is just the information that you get from the speed of sound (343 m/s) this means that you should count for 343 meters for every second you count between the flash and the thunder, all we need to do is change the units of the speed of sound to match the question (in our case, Km/s)

Best of luck.
