A - Explain Lightning Fatalities

  1. Hypothesize why most lightning fatalities occur at the beginning or end of a thunderstorm, rather than during the worst part of the storm. 

B - Math Applications

  1. If a lightning flash is seen 12 seconds before the thunder is heard, about how far away did the lightning strike?
  2. There are 5,280 feet per mile.  Use the "flash to bang" rule to figure out the speed of sound in feet per second.  
  3. There are 2.54 centimeters per inch, 12 inches per foot, and 100 centimeters per meter.  Convert your answer in Number 2 above to  meters per second.
