Answer:
9
Step-by-step explanation:
We are given
v = 18 m/hr west
θ1 = 285°
θ2 = 340°
After 1 hours, the distance traveled by the ship is
dv = 18 mi
The distance between the ship and the lighthouse is
d = 18 / cos 340
Solve for d<span />
youll get 2and 3/4 then divide by 2 and you get 1.0375=2 and 3/80
hope this helps!
