t = number of seconds
d = distance
then
d = t/5
sound travels about (1/5) mile per second
and
distance = speed * time
so the distance (d) is speed of sound (1/5) times the time (t) for sound to travel from lightning bolt to you.
DURING A THUNDER STORM AND LIGHTNING STORM, TO ESTIMATE HOW FAR AWAY THE STORM IS, COUNT THE NUMBER OS SECONDS BETWEEN THE TIME YOU SEELIGHTINING AND HEAR THUNDER. DIVIDE THAT NUMBER BY 5 TO FIND THE DISTANCE IN MILES TO THE STORM. WRITE A SENTENCE TO DESCRIBE THE PATTERN THAT THE FORMULA IS BASED ON. SET UP A TABLE TO SHOW THE TIME BETWEEN A LIGHTINGFLASH AND A THUNDERCLAP IF THE STORM IS 10,20,30,AND 40 MILES AWAY.
