Answer:

[tex] \sqrt{13} \: km[/tex]

[tex]the \: ship \: a \: ship \: b \: and \: lighthouse \: from \: a \: triangle. \: \\ the \: distance \: between \: the \: twoship[/tex]

[tex] = \sqrt{ {3}^{2} { + }^{2} - 2 \times 3 \times 4 \times \cos(60) } [/tex]

The answer is :

[tex] \sqrt{13} \: km[/tex]
