If you are on a train going at 50mph, and you pass a train going 50mph in the other direction, how fast are you going relative to that other train? (I think its 100mph but my friends disagree)

It's 100 mph , relative speed = total speed of the two trains .

But the other train is going 50mph as well so it should be double if it is relative to the other train, if you are just measuring the speed relative to the earth, yeah it would be 50mph
