In this problem, we're told that a total distance from anchorage to nome in the dog race is 1 ,049 miles.
00:09
It's a long distance.
00:12
We're also told that the musher m at a certain point is twice as far from anchorage, the starting point as he is from nome, the finishing point.
00:25
So we need to figure out how many miles has the musher traveled at that point.
00:29
So that's labeled the musher's distance from known as distance d.
00:38
And we're told that the distance from anchorage to the musher is twice as far.
00:43
So we'll say that's 2d.
00:47
So our equation becomes the total distance would equal 2d, what he's already completed, plus d, what he needs to still do.
00:57
And that will equal the total distance of the race, 1 ,049 miles.
01:01
So 3d is equal to 1 ,049, divided side by 3 to isolate d.
01:11
So we divide 1 ,049 divided by 3 in a calculator, that would come out to be 349 .6 repeating miles, almost 350 miles to go...
