Question

dog sled race extends 1049 miles, if a musher is twice as far from anchorage as from nome, how many miles has the musher completed,   round to the nearest whole number. can anyone help.

Answer 1

His distance from one end is ' D ', and his distance from the other end is ' 2D '.

The distance from one end to the other end is (D + 2D) = 3D .

3D = 1,049 miles

Divide each side by 3 :

D = 1,049 / 3 = 349 and 2/3 miles .

The question doesn't tell which end he started from, and where he's headed,
so I guess you have to know that this is the Iditerod race, it STARTS in Anchorage,
and it ENDS in Nome. 

He is ' 2D ' from Anchorage, so he has completed [ 2 x (349 and 2/3 miles) ] =
699 and 1/3 miles.

Rounded to the nearest mile, that's 699 miles.
