Many of us enjoy good math challenges, and there are tons of awesome places on the Internet where we can quench a math itch.
A couple of the best ones:

<p>As much as your "HUH-questions" are entertaining diversions, they might be bio_freaking out a lot of this forum participants.
Have mercy! SAT and AMC "are two big differences". </p>
<p>On your timely question.
I'd rather not use equations when I can do without them.</p>
<p>At the initial time when clocks S'n'F were set, they were
showing the same time.
1 hour later their readings differed by 62 - 56 = 6 min.
Correct time was (S clock) + 4 min. = (F clock) - 2 min.</p>
<p>2 hours later they differed by 2x62 - 2x56 = 2x(62-56) = 2x6 = 12 min.
Correct time: (S) + 2x4 min. = (F) - 2x2 min.</p>
<p>3 hours later: by 3x6 = 18 min.
Correct: (S) + 3x4 min. = (F) - 3x2 min.
....
When S and F struck 7 and 8 respectively, their readings differed by 60 min = 10x6 min.
Correct time at that moment:
(S) + 10x4 min. = 7:40 = (F) - 10x2 min.
It happened 10 hours past initial time.
10 hours back from 7:40 is 9:40.
THE END.</p>
