Watch
.
Answer :
If the 65 minutes
be counted on the face of
the same watch, then the problem would be impossible: for the hands
must coincide every 655/11
minutes as shown by its face, and it matters not whether it runs fast
or slow;
but if it is measured by true time, it gains 5/11
of a minute in 65 minutes, or 60/143
of a minute per hour.
