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?

Yeah, I got the same answer as you mark. 5:30 am.
Only through a more graphical method that would obviously require graphs to explain. So I wont here.

Weird how calculus and other methods dont agree. I wonder which ones right.
