Answer:

It's neither

Step-by-step explanation:

The only factor of 1 is 1.

A prime number has exactly two factors so 1 isn't prime.

A composite number has more than 2 factors, so 1 isn't composite either.

so... it's a neutral number.

Hope this helps!

There are 60 minutes in one hour, thus, 45 miles per hour is 45 miles per 60 minutes, thus

\bf \begin{array}{ccll}
miles&minutes\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
45&60\\
240&m
\end{array}\implies \cfrac{45}{240}=\cfrac{60}{m}\implies m=\cfrac{240\cdot 60}{45}
