Cannot sketch on these posts.
I'm sure you can sketch the diagram.
Then you can use the law of cosines to find
PR^2 = 6^2 + 13^2 - 2*6*13 cos89°
So you basically have a right triangle, with legs 6 and 13; figure the hypotenuse.

(I) sketch the diagram of his movement
(ii) calculate correct to the neatest kilometer, the distance PR
