Do you get less wet if you run in the rain?

I've spent a lot of time learning math (have a CS degree, which required lots of math). But sadly, I'm not comfortable enough with differential equations to come up with a solution like the first part. It makes sense once someone else has done it, but I wouldn't have gotten that far.

Perhaps I just need more practice. Practice makes perfect with math like everything else?

You don't really need much math to understand this. Imagine that a person is a perfect cube. The amount of rain hitting the top of this cube is constant-- does not depend on the speed of the cube. The amount of rain hitting the front of the cube is proportional to how fast the cube is moving. From this insight, everything else is algebra.

I was referring to coming with the differential equation first presented.

Understanding it is one thing, but coming up with it independently is different.

What contributes to how I feel when I arrive isn't the factor of my wetness, but how long I spent being rained on.

http://en.wikipedia.org/wiki/Peak-end_rule begs to differ.

It can beg all it wants, I'm still gonna run :)

I stop thinking about being in the rain as soon as I'm sheltered, so I'd rather minimize being in an unpleasant situation.
