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

I believe the probability is 1/2
Slope = (-2 + 7)/(9 - 3) = 5/6
y = mx + b
-7 = 5/6(3) + b
b = -7 - 5/2
b = - 19/2
equation
y = 5/6x - 19/2
standard form
5/6x - y = 19/2 or 5x - 6y = 57
