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

It measures the distance along the roads to the destination. I knows the speed limit. Time = distance / speed. That’s the travel time if there’s no traffic. But it knows if there is traffic because there are other people driving over there, and it can track how fast they’re all going because they have phones on GPS too. So if the cars on this one mile of road are going 20 mph instead of the 30 mph speed limit, it estimates you’re gonna go 20 mph there also, so the travel time is slower.
