We have the following kinematic equations that model the problem:
steam boat:
r1 = (36.8) * t
speed boat:
r2 = v * (t-1.75)
The distance between the boats is:
d = r2-r1 = v * (t-1.75) - (36.8) * t
Substituting t = 1.8 and d = 86.9 we have:
86.9 = v * (1.8-1.75) - (36.8) * 1.8
We clear the speed:
v = (86.9 + (36.8) * 1.8) / ((1.8-1.75))
v = 3062.8 Km / h
Answer:
the speed boats speed in km / h is:
v = 3062.8 Km / h
The mixture of the water will be 0.11286 I think it is
BC=QR would make it congruent
Answer:
x = 25.
Step-by-step explanation:
Move all of the terms that don't contain x to the right side and solve.
