Hello! We can solve this exercise using the rule of three.

First, let's write what we already know:

• 1 cm = 400km

,

• 26 cm = x km

Now, let's write it as two directly proportional quantities:


\begin{gathered} (1)/(26)=(400)/(x) \\ \\ \text{multiplying cross} \\ 1\cdot x=26\cdot400 \\ x=10400\operatorname{km} \end{gathered}

So, the distance between Maine and Japan is 10400km.
