Homework Help: Maths- Directions

A person moves towards north a distance 20m from point P and reaches at Q. He turns 135 degrees in clockwise direction and goes 40√2m. From here he turns 135 degrees clockwise and goes 25m. How far is he now from his initial position?

(If you could, could you explain with a rough illustration or something-for better understanding?)

Thanks!

sorry, bud -- no illustrations here.

P is at (0,0) PQ heading is N
Q is at (0,20) QR heaing is SE
R is at (40,-20) RS heading is W
S is at (15,-20)

PS is thus 25
