So what this is really giving us, this expression right over here is the average temperature. This is the average temperature over that time period. The integral of the temperature function divided by the total amount of time that has elapsed. And then using correct units, well the average temperature is once again going to be in degrees Celsius. And it makes sense because this right over here is in degrees Celsius. You're multiplying it by time right over here. But then you could divide by, you're dividing I'm assuming by time right over here.
