The sled dog race extends 1049 miles from Anchorage to Nome. If a musher is three times as far from Anchorage as from Nome, how many miles has the musher completed?

209.8 miles to go.

Step-by-step explanation:

The musher is x miles from nome.

The ,usher is 4x miles from anchorage.

4x + x = 5x = total distance = 1049 miles.

if 5x = 1049, then 4x = 4/5 * 1049 = 839.2 miles.

if 5x = 1049, then x = 1/5 * 1049 = 209.8 miles.

The musher has completed 839.2 miles and has 209.8 miles to go.

the first one, all those points on the line just make a strait line.

7 ft 6 in means 7 1/2, because 6 in is 1/2 of a foot. 7 ft 8 in means 7 2/3 because 8 in is 2/3 of a foot. 23/3 = 7 2/3. 15/2 = 7 1/2.

23/3   *   15/2   = 57 1/2
