$$ 5_c v 5_h = 5_p $$
$$ v = 5_p\frac{1}{5_c}\frac{1}{5} = \frac{1}{5} $$
We found that 1 cook makes $\frac{1}{5}$ of a pie within 1 hour. So his speed is $\frac{1}{5}p/h$.
$$ \text{25 cooks during 15 hours will bake} = \frac{1}{5} 25_c 15_h = 75_p $$
$$ \text{How much time it'll take to bake 15 pies for 25 cooks} = 3_h $$

$$ 5_c v 5_h = 5_p $$
$$ v = 5_p\frac{1}{5_c}\frac{1}{5} = \frac{1}{5} $$
