**Steve**, Friday, June 8, 2012 at 5:39amchange "bearing" to "heading" throughout.

Draw a diagram. Angle CAB = 60°, ABC = 90° and BCA = 30°

so, you have a 30-60-90 triangle, with the long leg=238.

short leg = 238/√3 = 137

and hypotenuse twice that or 274

so, the whole trip is 238+137+274=649 miles
