A railway-station clock shows 4:40. What time appears on its mirror image?

$11:60-4:40=7:20$: the minute hand on 8 is seen on 4, and the hour hand two-thirds of the way from 4 to 5 is seen one-third of the way from 7 to 8. 8:20 forgets to borrow, 7:40 keeps the minutes and 1:50 is the water image.
