So the integral from 0 to 10 of h of t is really the area of this entire, under this curve right over here. That's the integral, that's this part right over here. And then we're going to divide that by 10. 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.
