If you're on a 45mph road and someone puts themselves in your path 10 feet ahead, no, we don't say that you should have actually been going 5mph just in case something like this was going to happen. You're required to yield at crosswalks, but there's an expectation that mutual acknowledgement between you and the pedestrian happens at a reasonable distance before the pedestrian enters the roadway. Similarly, if someone enters an intersection on red, you have a duty to try and avoid the crash, but if it's too late, that's on them.

This is why roads should be designed not to cause such a situation. If you have a pedestrian path really close to a 45mph road the design is bad. I'm not aware of anywhere having such a high speed road where a pedestrian could walk along side it (in Netherlands). Usually it's more closed off with pedestrians being banned.

you can tell beforehand that its possible for somebody to suddenly jump out, so yes, you probably should be going 5mph

It's always possible for someone to enter the road, even a restricted-access freeway.
