3. You and a friend live 2 miles apart and are talking on the phone. You hear a crack of thunder and 8 seconds later your friend hears the crack. Find an equation that gives the possible places where the lightning could have occurred. (Use miles as the unit of distance. The speed of sound is about 1100 ft/sec.)
