The difference between the above velocities is that they exist in opposite direction of each other. or it can be said that they are negative vectors of each other.
Base SI unit is the unit that used for simple quantity like time=second and length= meter. They only have one unit.
Derived unit is more complex because you multiply or divide at least two base SI, making it have more than 1 unit. The example could be velocity which was time/length = m/s
