You have just purchased a nice new rose and now you must decide where to plant it. The only available position is in a rectangular garden bed between a rock wall which is 5 metres high and your side fence which is 2 metres high. The straight line distance between the rock wall and the fence is 3 metres. How far from the rock wall do you plant the rose in order to ensure that the plant receives the most hours of sunlight on a day when the sun passes directly overhead?
