Accepted Solution

A:

Answer: It will take 3.75 hours to reach 20°C.Solution:The bottle temperature begins at the freezer temperature of –16° CHow many hours will it take to reach 20° C?Change in temperature=20°C – (–16°C)Change in temperature=20°C+16°CChange in temperature=36°CThe bottle temperature will go up a steady 9.6° C every hour. Using a rule of three:9.6°C → 1 hour36°C → xx=(36°C)(1 hour)/(9.6°C) x=3.75 hoursAnswer: It will take 3.75 hours to reach 20°C.
