I. Optimization Train A leaves Union Station at 6:00pm and travels east at a speed of 110kmfh. Train B has been heading due south at 100kmfh and reaches Union Station at 7:00pm. {a} At what time between 6:00pm and 7:00pm were the two trains closest to each other? (b) What is the distance between the two train at this time? (c) At this time (from part b), which train is closer Union Station and by how much? Grading Scheme Generic Qgt'mizatign ghgggnsi; Ensure you have all components to achieve full marks _ Drawing of a fullylabelled image that represents the given optimization scenario ; All related variables/functions defined ; Algebraic steps are clear and thorough ; Justification included regarding whether the critical point represents a maximum or minimum {local or absolute?) Final conclusion statement
