D) 15 hours

Answer 1

The temperatures in Coldspot and Frostburg will be the same after 4 hours.

Step-by-step explanation:

To find out how long it will be until the temperatures in Coldspot and Frostburg are the same, we need to set up an equation.

The equation can be represented as:

-7 + 2.5x = 19 - 4x

where x is the number of hours it will take for the temperatures to be the same.

Solving this equation, we get:

6.5x = 26

x = 4

Therefore, it will take 4 hours until the temperatures in Coldspot and Frostburg are the same.
