**Reiny**, Sunday, March 10, 2013 at 9:10ammake a sketch, you should get an isosceles triangle with equal legs of 6(10/60) or 1 km, and vertex angle of 68°

let the base be 2x, and each of the base angles will be 56°

cos 56° = x/1

x = .55919..

2x = 1.118..

they will be 1.118 km apart

or

we could use the cosine law:

distance^2 = 1^1 + 1^2 - 2(1)(1)cos68°

= 2 - 2cos68° = 1.25078..

distance = √1.25078.. = 1.118 , same as above
