Remember, these are vectors - direction matters. Look at the direction of your arrow of and . Now look at how you're travelling from B to C and then from C to D. When you're going from C to D, your direction of travel is opposite that of , so you're moving units to go from C to D.

d) You've also used the wrong sign for DC
