D=4(9-c) and d=2(9+c)
d=36-4c and d=18+2c
Since d=d
18+2c=36-4c add 4c to both sides
18+6c=36 subtract 18 from both sides
6c=18 divide both sides by 6
c=3
So the speed of the current is 3mph

<u><em>Solution:</em></u>
We have to find the value of "n" in the proportion
<em><u>Given proportion is:</u></em>
<em><u></u></em>
<em><u></u></em>
We can solve the above proportion by cross-multiplying
Multiply the numerator of the left-hand fraction by the denominator of the right-hand fraction
Multiply the numerator of the right-hand fraction by the denominator of the left-hand fraction
Set the two products equal to each other
Solve for the variable




Thus the value of n in given proportion is 16
