Exactly 5.5 seconds after a rubber ball has been dropped into a well, a splash is heard. The speed of sound is 1100 ft/sec. How far is the top of the well from the water? Hint: The distance that a dropped object falls in t seconds is represented by the formula $s = 16t^2$. The well is approximately deep. (Round to the nearest tenth as needed.)
