3.
[5, -8] + [0, -5] + [-7, 0] + [0, -6] = [-2, -19] --> III. Quadrant
4.
[-2, 6] + [0, 3] + [5, 0] + [0, 4] = [3, 13] --> I. Quadrant
5.
[0, -5] + [-5, 0] + [0, 4] + [7, 0] + [0, -3] = [2, -4] --> IV. Quadrant

Answer:
elephant: 25 mph; zebra: 40 mph
Step-by-step explanation:
The time required is the same in each case, so we need to set up an equation of the form distance1/speed1 = distance2/speed2:
8 miles 5 miles
------------- = time = -------------
speedz speede
From this we get:
8 5
------------------ = -------------------
speede + 15 speede
Cross multiplying, we get: 8(speed e) = 5(speede) + 75, or
3(speede) = 75, or
speede = 25 mph
Then speedz = 25 mph + 15 mph = 40 mph = speedz
