My kitchen clock is working properly but was showing 14:02, which I know is the wrong time, when I left to walk to my friend’s house for coffee. My friend’s clock, which is correct, was showing 14:25 when I arrived and 15:08 when I left. I walked home at the same speed as when I went, and when I arrived home my clock was showing 15:56. I then adjusted my clock to the correct time. How many minutes and which direction did I have to adjust my clock?
