One morning it starts to snow at a constant rate. Later, at 6:00am, a snow plow sets out to clear a straight street. The plow can remove a fixed volume of snow per unit time.
If the plow covered twice as much distance in the first hour as the second hour, what time did it start snowing?
(In reply to

That would work if the plow moved at a constant rate for each hour, based on the average depth of the snow for that hour. Since, however, both are constantly changing, the calculus is required.
