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
Twice is not twice by P C)
That is just the point; it is not the
average during the first hour that counts. The plow moves snow at a
constant rate (per volume), which is why calculus is needed to account
for the changing depth of snow at the same time it is being removed.
.. That's why you didn't get the correct answer ...
