In order to solve this, just subtract 45 from 63.

So,
63-45 = 18 km

To get the direction, just copy the one with the greater magnitude/numerical value, that is, due east

Thus, the answer is 18 km due East.

Good luck and God bless!

63 km east - 45km west =18km east of its start point, facing west.
