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 />
        
             
        
        
        
First we have - 6 < - 7 - 4x 
Then we need to isolate the x of the inequality 4x < - 7 + 6
 4x < - 1
 x < - 1/4 
The values less than - 1/4 are solutions for x
