i think i can figure it out i just do not understand what to do when it says "relative"
 
Relative means from that person's point of view, so you have to take that person's speed and position into account when you work out the other person's speed and position.
 
i think i got it

ok so sabrina's position and velocity relative to lauren would be 20 km west traveling 45 km/hr west

lauren's position and velocity relative to sabrina would be 20 km east traveling 45km/hr east

and lauren's postion relative to chris would be 10 km east
