About 390 km because you drive 130 km per hour so 130 times 3 is 390

Answer:

390 KM

Step-by-step explanation:

Every 130 kilometers, an hour passes by. This means, that if you drive for 3 hours, you must multiply those 130 kilometers by 3.

130*3=<u>390</u>

$\bf \textit{we know that }

100\cdot 78.7=k\sqrt[3]{48820}\implies \cfrac{7870}{\sqrt[3]{48820}}=k

thus\qquad \boxed{p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{w}}{s}}
\\\\\\
\textit{now, what is \underline{p} when }
\begin{cases}
w=54,688\\
s=72.6
\end{cases}?\implies p=\cfrac{\frac{7870}{\sqrt[3]{48820}}\sqrt[3]{54688}}{72.6}$

now, if that value is less than 100, then the fellow is "undernourished", otherwise, is overfed.
