Same d = rt
so the boat's still water speed is 20kph, if we... say the current of the river is "r", then, when the boat was going upstream, its speed was " 20 - r", and when it was going downstream, is " 20 + r", since the river's current is adding speed to it
again, if on the way up, it took "t" hours, on the way down, it took the slack of the 3hrs, or " 3 - t"
thus
solve for "r"

<h3>Answer:</h3>
- hole: x = -4
- vertical asymptote: x = 1
- horizontal asymptote: y = -1
The function factors as ...
... f(x) = -(x+3)(x+4)/((x-1)(x+4)) = -(x+3)/(x-1) . . . . x ≠ -4
and the quotient is ...
... f(x) = -(1 +4/(x-1))
... f(x) = -1 -4/(x-1) . . . . . x ≠ -4
This has a hole at x = -4 (where the denominator factor cancels the numerator factor), a vertical asymptote at x=1 (where the denominator is zero), and a horizontal asymptote at y = -1 (the value of the function for large values of x).
