- TL;DR Summary
- Should you run or walk in the rain to become least wet. You should go as quickly as possible.
I have seen running or walking in the rain puzzle many times. I have not seen a quick answer to the question yet. I was provoked, when a newspaper claimed a professor had been studying it a bit and came up an answer. Honestly I doubt anyone has studied.
My answer is that one should go as quickly as possible. One can imagine two perpendicular cross sections of a body. One is along the horizontal direction of motion and another vertical. The horizontal part scoops water droplets between the start and the end positions. Since the density of water droplets in the air is constant in place and time, the amount one scoops is constant. The vertical cross section scoops as long as one is in the rain, so one should minimize the duration.
