During a thunderstorm you see the lightning before you hear the thunder because light travels much faster than sound. The distance between you and the storm varies directly as the time elapsed between the lightning and the thunder. Suppose that the thunder from a storm 1.7 miles away from you takes 8 seconds to reach you. (a) Write an equation for the distance D between you and the storm in terms of the time t elapsed between the lightning and thunder. (b) If you later observe a 14-second interval between the lightning and thunder, how far away is the storm?
