Question

A bottle 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?

Answer 1

It is given that the bottle temperature begins at the freezer temperature of –16° C. Thus, the initial temperature is –16° C.

Now, sitting on the kitchen counter, the bottle temperature will go up a steady 9.6° C every hour. We need to know how many hours will it take to reach 20° C.

Let us assume that it will take "$x$" hours to reach the required temperature. Then the equation that will guide this system will be a linear one as shown below:

$-16+9.6x=20$

Adding 16 to both sides we get:

$9.6x=20+16=36$

Dividing both sides by 9.6 we get:

$x=\frac{36}{9.6}=3.75$ hours

Thus it will take 3.75 hours (or 3 hours 45 minutes) for the bottle of maple syrup to reach a temperature of $20^{\circ}$ celsius.
