Answer:

It will be 4 hours until the temperatures are the same

Step-by-step explanation:

Let $T_{c}$ represent the temperature in Coldspot in $x$ hours and

$T_{f}$ represent the temperature in Frostberg in $x$ hours.

From the question,

The temperature in Coldspot is -7° and is increasing 2.5° per hour, then we can write that

$T_{c} = -7 + 2.5x$

Also, from the question,

The temperature in Frostberg is 19° and is decreasing 4° per hour, then we can write that

$T_{f} = 19 - 4x$

To determine how long it will be until the temperatures are the same, that is when $T_{c}$ will be equal to $T_{f}$ , we will equate the two equations and determine $x$ .

$x$ will give the number of hours until the temperatures are the same.

$T_{c} = T_{f}$
