Abottle of maple syrup in wayne’s freezer needs to be warmed for breakfast. sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° c every hour. if the bottle temperature begins at the freezer temperature of –16° c, how many hours will it take to reach 20° c? change in temperature: (20 – (–16)) = 20 + 16 = 36 hours

It will take 3.75 hours to reach 20°C.

Solution:

The bottle temperature begins at the freezer temperature of –16° C

How many hours will it take to reach 20° C?

Change in temperature=20°C – (–16°C)

Change in temperature=20°C+16°C

Change in temperature=36°C

The bottle temperature will go up a steady 9.6° C every hour. Using a rule of three:

9.6°C  →  1 hour

36°C   →   x

x=(36°C)(1 hour)/(9.6°C)

x=3.75 hours

It will take 3.75 hours to reach 20°C.

The answer would be 3.75

trust me I checked

Hope it helps
