Light and sound both travel at finite speeds, but the speed of light is much, much greater than the speed of sound. both travel at near constant speeds in air and this fact can be used to judge the approximate distance to an incoming storm. assume that the speed of sound in air is approximately 340.00 m/s. one night you see a flash of lighting and ten seconds later you hear the thunder caused by the lightning flash. approximately how far away, in miles, is the storm from your location? (just find the time sound travels in ten seconds moving at a constant speed.) 1. a.) 4.11 mi b.) 2.11 mi c.) 8.22 mi d.) 3400.00 mi e.) none of the above.
