A common method for estimating the distance to
a lightning flash is to begin counting when the flash is
observed and continue until the thunder clap is heard.
The number of seconds counted is then divided by 3 to
get the distance in kilometers. What is the velocity
of sound in kilometers per second?
(The speed of light is 3*10^8 m/s.)
I have no idea how to start this problem, please help?
