Hello,

36 km

Since were 2 of 7 hours for tourism, drew the only ship for 5 hours. Since the distance / time = rate then:

.. x. ..... x
---.+.--- = 5
12 ... 18

Multiply eliminate any period of 36 fractions.


36x ... 36x
---.+.--- = 36 (5)
12 ... 18

3x + 2x = 180
5x = 180
x = 36, when the vessel 36 miles in each direction on the trip.

Hope this helps! :-)
