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.

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. 
If sound travels 1129 feet per second through the air, then what would an equation be that represents how many feet sound can travel in 2 seconds?
