15/3 = 5 ... storm distance in km
15s * 343m/s = theoretical distance
the time for the light to travel is below the sig fig of the other measurements ... it can be considered instantaneous
If we have just counted 15 seconds between the lightning and thunder, how far away do we predict the center of the thunderstorm to be using the 3 second rule and What was the percent difference between the prediction and the real distance of the thunderstorm? The speed of light is 3x108 m/s, and the speed of sound is 343 m/s.
