Expert Answer
If the two velocities act in one dimension only, then we either add/subtract the two to get the relative velocity. And if the two velocities act perpendicular to each other (i.e. in a plane), we use pythagorus theorem to find the relative velocity.
However, the general formula for the relative velocity is
