Staying at your computer for an hour, and grinding until you figure out the solution?
Going for a 40 minute walk and figuring out the solution?
North America has a "sitting paradigm" for doing work. If the boss sees you staring at your monitor he might assume that you're working.

Sitting at a workstation doesn't equal working hard. Stand up, get out. Problem solved.
