tan 30 degrees = x/45 => x=~ 30 km

tan 40 degrees = x/22.5 => x~= 19 km

?? :surprised

15 min (same vel) later another man spots the castle in an 40-degrees angle

And this other man, where is he located?

In the car he also.

So you have two right triangles with a common side, the road to the castle. One has an angle of 30 degrees and a side of 45 km. The other triangle has a angle of 40 degrees and a side of 22.5 km,
