"One day it started snowing in the morning at a heavy and steady rate. A snowplow started out at noon, going 2 miles in the first hour and 1 mile in the second hour. What time did it start snowing?" Say what?! This is a famous problem from the 1942 book "Differential Equations" by Ralph Palmer Agnew. I came across it on Roy Wright's blog (https://roywright.me/2018/03/0....1/favorite-math-prob You can assume the snowplow's speed is inversely proportional to the snow that has fallen. And then, using the magic of calculus, we can find an answer! Watch the video for a solution.
