Two objects fly toward you, one from the east with speed u, and the other from the west with speed v. Is it correct that their relative speed, as measured by you, is u + v? Or should you use the velocity-addition formula, V = (u + v) / (1 + uv/c2)? Is it possible for their relative speed, as measured by you, to exceed c?
