Do the front and back bikers have to pedal at the same speed? If the front biker is pedaling faster than the back biker, how can 2 gears rotating at different speeds work together? As a kid I used to just assume the back pedals were fake and not connected to anything.

It’s part of the same drive train. So they will be doing it simultaneously. You just have to synchronize.
But there are multiple variations. Even with separate drive trains.
