Answer:
Option D: 20km South
Step-by-step explanation:
Lets say A = (0, 0)
A is 30km East of D which makes D = (-30, 0)
D is 10km South of F which makes F = (-30, 10)
F is 10km West of B which makes B = (-20, 10)
A is 10km North of C which makes C = (0, -10)
C is 20km East of E which makes E = (-20, -10)
Find distance from B = (-20, 10) to E = (-20, -10)
1. Cancel equivalent values:
x of B = (-20) and x of E = (-20)
Remove x from equation.
2. Solve for answer:
B = 10 and E = (-10)
Find the difference: (-10) - 10 = (-20)
Conclusion:
South translates to negative on a graph making the answer 20km South
