the iditarod sled dog race extends 1049 miles for anchorage to nome. If a musher is three times as far from anchorage as from nome, how mant miles has the musher completed?
Answer provided by our tutors
musher is x miles from nome.
musher 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.
-----
musher has completed 839.2 miles and has 209.8 miles to go
