A lake near the Arctic Circle is covered by a 2 22-meter-thick sheet of ice during the cold winter months. When spring arrives, the warm air gradually melts the ice, causing its thickness to decrease at a constant rate. After 3 33 weeks, the sheet is only 1 . 2 5 1.251, point, 25 meters thick. Let S ( t ) S(t)S, left parenthesis, t, right parenthesis denote the ice sheet's thickness S SS (measured in meters) as a function of time t tt (measured in weeks).
