Excercise 55 Suppose that a point is moving from A(0, 10) towards the origin along the second coordinate axis with constant speed 5 m/s. At the same time another one is moving from B(10,0) towards the origin along the first coordinate axis with constant speed 3 m/s. Find to to minimize the distance between the moving points provided that they simultaneously started.
