Your watch is playing up again. It was correct at midnight but since then it has lost exactly 8 minutes every hour. The watch stopped an hour ago in the afternoon showing 4.15. What is the correct time now?
if you multiply 16.25 by 8 ,that gives you the minutes that have been lost . Add that to 5.15 and that's the time now . would work it out for but I'm having my tea at present . !
regards
ive done it as though the watch loses 8 minutes for every real hour but perhaps it means that the watch is 8 minutes behind when it shows an hour has passed
