I drew the vector for ship # 1 @ 0 deg
and ship # 2 @ 140 deg.
d1 = 26 mi / h * 3 h = 78 mi @ 0 deg.
d2 = 34 mi / h * 3 h = 102 mi @ 140 deg.
d = 102 mi @ 140 deg - 78 mi @ 0 deg.
X = hor = 102 * cos140 - 78cos0,
= -78.1 - 78 = - 156.1 mi.
Y = ver = 102sin140 - 78sin0
= 65.6 - 0 = 65.6 mi.
d^2 = x^2 + y^2,
= 24367.2 + 4298.7,
= 28665.9,
d = sqrt(28665.9) = 169.3 miles apart.
