On a playing ground A, B, C, D, E face North: B is 50 m right of D; A is 60 m south of B; C is 40 m west of D; E is 80 m north of A. If a boy walks C → D → B → A → E in straight lines, total distance (m)?
A120
B150
C170
D230
Answer & Solution
Correct answer: D. 230
1. Set coordinates: D=(0,0); B=(50,0); C=(-40,0); A=(50,-60); E=(50,20).
2. Distances: C→D = 40; D→B = 50; B→A = 60; A→E = 80.
3. Total = 40 + 50 + 60 + 80 = 230.
