Answer:
   about 2.81 km/h
Step-by-step explanation:
It can be useful to draw a diagram.
The lines pointing to due north from points B and P are parallel, so the angle BCP and the bearing of point C from P are the same, 30°. The angle BPC will be the difference of bearings of B and C at P, so is 47-30=17°. This is enough information to solve the triangle using the Law of Sines:
   PB/sin(C) = CB/sin(P)
   CB = PB·sin(P)/sin(C) = (1200 m)·sin(17°)/sin(30°) ≈ 701.7 m
The speed of the boat is then ...
   x = distance/time = (0.7017 km)/(1/4 h) = 2.8068 km/h
 
        
             
        
        
        
1/7w-5 ???? That might be right not sure tho
        
             
        
        
        
The budget of Van for groceries for 1 week is:
12 $ (per a weekday) * 5 (weekdays) + 15 $(per a weekend day) *2 (weekend days) = 60$ +30$ = 90$
The budget of Van for w weeks is:
90 $ (per week) * w (weeks) = 90w dollars.
Answer: 90w $
        
             
        
        
        
A+(n-1)d=nth term
