Lightning (Refer to Exercise 1.) Doppler radar shows an electrical storm 2.5 miles away. If you see the lightning from this storm, how long will it be before you hear the thunder?

Exercise 1

Lightning If there is an x-second delay between seeing a flash of lightning and hearing the thunder, then the lightning is miles away. Suppose that the time delay between a flash of lightning and the sound of thunder is 12 seconds. How far away is the lightning?
