Plane moves 10 times faster than boat.  So if boat moved at 10mph, plane would be 100mph.  (Guess and check)  After two hours where would they be?  Boat will have moved 20mi in addition to the 180 for 200mi in total.  Plane will have moved 100x2=200mi.  Therefore the answer would be 200mi.

Ship has already travelled 180 miles
when ship travels 1 mile more the plane would 10 miles
ship: 20 more miles -> plane:200m and they meet each other
Ans: 200m
 
Hope I am clear.
