She starts out at the coordinates x = + 400 m, y = + 200 m, as shown in the figure. First she undergoes a displacement D, = - 700m / - 100m ) , traveling a distance of 800 m in 3 hours. Next she undergoes a displacement D, = 200 m i - 300 m / , traveling a distance of 500 m in 2 hours. Then she stops to rest, for 1 hour. Finally, she undergoes a displacement , with scalar components D3, = + 500 m, D, = -100 m, while moving through a distance of 1200 m in 4 hours. ^ty (m) + 300 200 + 100 +x (m) - 400 - 300 - 200 - 100 100 200 300 400 -- 100 - 200 - - 30011.

First, the turtle travels through a displacement D1 = 4.00 km, directed 40.0' W of S. N (+y) Then the turtle undergoes a displacement D2 = 5.00 km, directed 70.0' S of E. E (+x) Thus, the turtle undergoes a resultant displacement R = D + D. .
