A car travels with a velocity of 90 km/h on a stright line. And a man in the car saw a castle left of the road. The angle the straight line to the castle from the cars position was 30 degrees. 15 min (same vel) later another man spots the castle in an 40-degrees angle. After another 15 min they spot a perpendicular way towards the castle. How long is this way in to the castle?
tan 30 degrees = x/45 => x=~ 30 km
tan 40 degrees = x/22.5 => x~= 19 km
?? :surprised
