Problem
Object P is initially 30 m east of an intersection and moves east at 6 m/s. At the same instant, Object Q is 40 m north of the intersection and moves south at 8 m/s. Indicate whether the distance between the two objects is increasing or decreasing at that initial instant, and justify your conclusion with one brief calculation or statement.
