Eli5 how does the GPS know exactly how Long it will take you to get somewhere? Factoring in driving at different speeds or unforseen traffic that’s an hour away

Looks like you got answers to the question.
But, I’m going to point out that GPS, the “Global Positioning System/Satellite(?)”, knows nothing about the roads, traffic, historical travel times, direction of travel, origins, destinations, nothing. It *only* knows (approximately) where you currently are.
ALL of the rest regarding navigation and travel times is dealt with by software on your device or a server to which your device is connected.
