A man starts from point P, walks 10 m North, turns left and walks 15 m, turns left again and walks 25 m, then turns right and walks 5 m. How far is he from P?

A20 m
B35 m
C30 m
D25 m

Correct answer: D

Explanation

His path is North 10, West 15, South 25 and West 5, so he is 20 m west and 15 m south of P; the distance is √(20² + 15²) = 25 m.
