First, use the Pythagorean Theorem, then use equation

#### Explanation:

Object A has moved

Object B has moved

The velocity of Object A is then

The velocity of Object B is then

Since these objects are moving in opposite directions, these velocities will add, so they will appear to be moving at 3.10 m/s

away from each other.
