    I'm assuming that you want to know how many hours until they are the same temperature. Here is the equation you can use to figure it out:

    40 + 5h = 340-45h

    Here is how I would solve it:

    40 + 5h = 340 - 45h

    +45 h + 45 h

    40+50h = 340

    -40 - 40

    50h = 300

    /50 / 50

    h = 6

    It will take 6 hours for the two appliances to reach the same temperature, assuming the power doesn't go out. For reference, they would be at 80 degrees.
