A plant produces 100 MW at noon and 140 MW at 6 pm. The average production over the interval is?

Explanation:
When a quantity changes at a constant rate over a time interval, the average value during that interval is the midpoint between its end values. Here the plant goes from 100 MW at noon to 140 MW at 6 pm, so assuming a linear change, the average production is (100 + 140) / 2 = 120 MW. Therefore, the average over the interval is 120 MW.
