We have been traveling for 5 days since leaving the
Ivotuk Cabin. It is now time to determine whether we
will have enough snowmachine gasoline to get to
Barrow.
We left Ivotuk with six full snowmachines (four hold 8
gallons of gas each, and two hold 10 gallons of gas
each), plus 28 jugs that each hold 5 gallons of gas.
The total straightline distance from Ivotuk to Barrow
is 250 miles. But because we are not able to travel in
a straight line (for example, we follow rivers, go
around mountains and hills, and avoid big snow
drifts), our actual distance traveled is increased by
roughly 30%. Two of our snow machines get 8 miles per
gallon, two of the others get 10 miles per gallon, and
the last two get 12 miles per gallon.
Questions:
1) Will we make it to Barrow with this amount of gas?
2) If not, how many miles away from Barrow will we run
out of gas?
3) How far would the 30% distance factor have to be
reduced to just make it to Barrow without running out
of gas?
SOLUTION:
We started with a total of 192 gallons of gas (52 in
snowmachines, 140 in jugs).
The total miles traveled from Ivotuk to Barrow will be
325 miles (250 * 1.30 = 325).
The average fuel consumption, considering all of our
snowmachines is 10 miles per gallon ((2*8 + 2*10 +
2*12) / 6 = 10).
On average each snowmachine will have 32 gallons of
gas for the trip (192/6 = 32). This will allow us to
go 320 miles (32 * 10 = 320).
If our 30% distance factor can be reduced by 2%, to
28%, we will make it the entire 325 miles to Barrow
(so we need to make sure we go in straight lines as
much as possible, or we might be walking!).
Answers:
1) No, under these conditions we will not make it to
Barrow with this gas.
2) We will run out of gas 5 miles from Barrow.
3) The distance factor would have to be reduced to 28%
in order to make it to Barrow (a reduction of 2%).
WHERE IS MRS. CHEUVRONT??? LET'S PLOT!!!

The winds went away today. They had mysteriously left
as they had appeared. The winds left their mark
leaving behind beautiful sculpted snow. Snow had been
transformed, moved, drifted into new art pieces. As
we ascended out of our hiding place, it was hard to
imagine that we stood in the same location where the
world was fierce and brutal yesterday. Today the
white world was peaceful, serene.Cold but peaceful.
Cold was manageable. The wind was too hurtful and
unforgiving.
We our on our trek northward to Ataqasuk. The
landscape and terrain has changed. We our traveling
across rolling hills. All the vegetation is covered
with snow. We cross over drainage basins that in the
summer allow the water to flow. Crossings can be
difficult at times and sleds are unhitched and
rehitched to move stuck snowmachines. Tonight
we camp in the Oumalick River that is covered with
snow. We are protected from any wind that may arise by
large snowdrifts.
Temperature min: 32 degrees Celsius
Temperature max: 17 degrees Celsius
