For the sake of convenience, let us label ships A and B
As shown in the figure, the distances to the ships from right triangles.
The distance to the ship A is 
and it is given by
And the distance to the ship B is 
and is given by
Therefore, the distance

Answer:
c= 3
Step-by-step explanation:
0.2(10 -5c)= 5c -16
<em>Expand</em><em>:</em>
0.2(10) +0.2(-5c)= 5c -16
2 -c= 5c -16
<em>Bring</em><em> </em><em>all</em><em> </em><em>c</em><em> </em><em>terms</em><em> </em><em>to</em><em> </em><em>1</em><em> </em><em>side</em><em>,</em><em> </em><em>constant</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>other</em><em>:</em>
5c +c= 2 +16
<em>Simplify</em><em>:</em>
6c= 18
<em>Divide</em><em> </em><em>by</em><em> </em><em>6</em><em> </em><em>on</em><em> </em><em>both</em><em> </em><em>sides</em><em>:</em>
c= 18 ÷6
c= 3
