What is the "true" distance an object travels based on relative speeds?

There are two objects (x and y) with x travelling at 10km/h and y travelling at 11km/h, both with respect to the earth. After 1h, from the perspective of the earth, y travels 11km, but from the ...

Discretizing kinematics of moving object

I think this is a simple question, but I'm unable to find the relationship: The relative distance between two objects at any time $t$ can be written as: $x_r(t)=x_{ro}+\int_{t_0}^{t_f}v_r(t)dt$ where: ...
