The correct option is: c. 3.16 miles per hour.

Step-by-step explanation:

Suppose, the rate of the current = x mph.

Speed of the boat is mph in still water.

So, speed of the boat in upstream = (4-x) mph and speed of the boat in downstream =(4+x) mph

We know, $Time= \frac{Distance}{Speed}$

For upstream, distance = 6 miles and speed =(4-x) mph

So, the time taken in upstream $=\frac{6}{4-x}$ hours

For downstream, distance = 6 miles and speed =(4+x) mph

So, the time taken in downstream $= \frac{6}{4+x}$ hours

Now the total time taken for upstream and downstream is hours, so the equation will be.....

$\frac{6}{4-x}+\frac{6}{4+x}= 8\\ \\ \frac{24+6x+24-6x}{(4-x)(4+x)}=8\\ \\ \frac{48}{16-x^2}=8\\ \\ 8(16-x^2)=48\\ \\ 16-x^2=\frac{48}{8}\\ \\ 16-x^2=6\\ \\ -x^2=6-16\\ \\ -x^2=-10\\ \\ x^2=10\\ \\ x=\sqrt{10}\approx 3.16$

So, the rate of the current is 3.16 miles per hour.
