Question:
A man is watching from the top of a tower a boat speeding away from the tower. The boat makes an angle of depression of \(45\degree\)with the man's eye when at a distance of 60 meters from the tower. After 5 seconds, the angle of depression become \(30\degree\). What is the approximate speed of the boat, assuming that it is running in still water?
