+62 Suppose that the minute hand of a clock is 15 mm long and the hour hand is
12 mm. How fast is the distance between the hour hand and the minute hand
changing at 2 pm?
Note: This time, assume that both the hour and minute hands are moving!
My final answer was -0.018141 mm/s. Could someone please verify this for me? I tried manipulating the cosine rule for this question.
