S1 = speed of boat 1
<span> t1 = time to do 1400 meters (boat 1) </span>
S1*t1 = 1400
<span><span>S2 </span>= speed of boat 2 </span>
1400 + S2*t1 = X
t2 = time to do X + 600 (boat 2)
S1*t2 = X + 600
S2*t2 = 2X - 600
S1 = 1400/t1
S2 = (X-1400)/t1
<span>T = t2/t1 </span>
1400*T = X + 600
X*T - 1400*T = 2X - 600
X = 3600 meters
<span> River is 3600 meters wide</span>
C is the correct answer! hope this helped
There's no way to tell with the given information.
You've given us one point on a graph . . . (-15, 12) .
There are an infinite number of different lines that can
go through that point. We don't know anything about
the function (how 'y' depends on 'x'), so we have no way
to know any other point on the graph.
Wait this is easy just check all the angles then times them then you divide what you got and boom. You got you answer.
