Ice on a lake gets thicker as long as the temperature is below freezing. On a certain lake it took 8 days for the ice to reach a thickness of 3 inches.
(a) At what rate was the ice growing over these 8 days in inches per day? Do not round your
decimal answer
(b) Ice is safe to walk on when it is 10 inches thick. Would this ice be safe after 3 weeks if it
grew at the rate in (a)?
(c) The ice will stop growing if it reaches a thickness of 1.5 feet. At the rate in (a), how many
days of freezing would this take? First, think about how many inches 1.5 feet represents.
