8. 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° with the man’s eye when at a distance of 60 meters from the tower. After 5
seconds, the angle of depression becomes 30. What is the approximate speed of the boat, assuming
that it is running in still water?
