Snow Big Deal
You are standing on a straight road in the middle of a snowy field. Your maximum walking speed is 4 mph on the road, and 2 mph in the field. Let A be the area, in square miles, of the region of the field you could reach within an hour. Find \(\lfloor 10A \rfloor\).
Details and assumptions
- The width of the road is negligible.
- You can be walking in any direction at any time.
- You don't need to be walking for the entire hour.
