For Kishore Karra, the most difficult
of the questions posed in the Dirty
Dozen Puzzle Contest was what time
the snowfall began.
A snowplow at a Keystone, Colo.
, resort works at a rate inversely proportional to the depth of snow on the road.
The snowplow starts at 9 a.
m.
and travels one mile in the first hour, then onehalf mile in the second hour.
It took Karra about as long as the
snowplow to figure it out.
The answer is
8:30 a.
m.
“I wasn’t really sure about that one,”
the computer science engineering senior said.
“The
calculations weren’t really
all that hard.
It’s just waiting for the idea to strike
you.
”
Karra won $1,000 and
in-state tuition rates for 3
semesters with his winning submission
in the Dirty Dozen competition.
He is
the second personto answer all 13 questions correctlysince thecontest began in
2000.
The snowplow problem — the
one Karra found difficult — was No.
13,
the trick question of the baker’s dozen.
