A plant produces 120 MW at noon and 180 MW at 6 pm. The average production over the interval is?

Explanation:
To find the average production over a time interval when you know the values at the endpoints, you take the mean of those end values (assuming a roughly linear change between them). Here, production is 120 MW at noon and 180 MW at 6 pm, so the average is (120 + 180) / 2 = 150 MW. This reflects the typical level during the period as the plant rises from 120 to 180 MW. The endpoint values (120 or 180) would be the production at a specific time, and 300 MW would be the sum, not the average.
