The equation D= 0.2s represents the approximate distance, d, in miles of a thunderstorm when s, seconds, pass between a flash of lighting and the sound of thunder. About how far is the thunderstorm from each student listed in the table. Draw a graph that represents the relationship between the time between lighting and thunder and the distance of the storm from the student. Student/Time between flash and sound: Sandy; 5 Diego; 9 Ted; 4 Cecilia; 11 Massoud; 8
Distance: Sandy; 1.0, Diego; 1.8, Ted; 0.8, Cecilia; 2.2, Massoud; 1.6 Points (s,d): (5,1) , (9,1.8) , (4,0.8) , (11,2.2) , (8,1.6)
