1. An army recruit is on a training exercise and instructed to walk due west for 8 km,
then in a north-easterly direction for 4 mi, and finally due north for 15,840 ft. How far
will he be from where he started?
2. A tittle turtle is placed at the origin of an xy grid drawn on a large sheet of paper.
Each grid box is 1.0 cm by 1.0 cm. The turtle walks around for a while and finally
ends up at point (24, 10), that is, 24 boxes along the x-axis, and 10 boxes along the
y-axis. Determine the displacement of the turtle from the origin at the point.
3. A bug starts at point A, crawls 8.0 cm east, then 5.0 cm south, 3.0 cm west, and 4.0
cm north to point B. (a) How far north and east is B from A? (b) Find the
displacement from A to B both graphically and algebraically.
4. A woman jogs 4.2 km east and then 2.9 km south at a speed of 8.0 km/h. How much
time would she have saved if she had jogged directly to her destination?
