Just divide 672 revolutions by 39 & 1/9 revolutions per minute. The units may seem wrong but will easily work themselves out to minutes.

$\Huge \boxed{k=4}$

Step-by-step explanation:

$\sf 3k+16=8+5k$

Subtracting 3k and 8 from both sides.

$\sf 16-8=5k-3k$

$\sf 8=2k$

Dividing both sides by 2.

$\sf \displaystyle \frac{8}{2} =\frac{2k}{2}$

$\sf 4=k$
