]]>Boat stationed at C forms a 30-60 - 90 triangle (COA), Hence ratio of sides :

AO : OC : AC = 1 : sqrt3 : 2

OC = 300 sqrt 3

Similarly boat stationed at East of the lighthouse forms a 45 - 45 - 90 triangle.

Ratio of the sides 1 :1 : sqrt 2

OB = 300

OA = Height of the light house

C : Boat stationed at North

B : Boat stationed at East

Shortest distance between boats : BC

BC^2 = OC^2 + OB^2

BC^2 = 300^2 +(300sqrt3)^2

BC = 600.

lighthouse. Simultaneously, another boat, stationed at the East of the same lighthouse, is making an angle

of 45° with the top of the lighthouse. What will be the shortest distance between these two boats? The

height of the lighthouse is 300 feet. Assume both the boats are of negligible dimensions.

Options:

1) 300 feet

2) 600/√3 feet

3) 300√3 feet

4) 600 feet

5) None of the above]]>
