On December $17,$ $1903,$ at Kitty Hawk, N.C., the $1903$ Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard.

\begin{tabular}[t]{|l|c|c|c|}
\multicolumn{4}{c}{\textbf{December 17, 1903 Flights}}\\\hline
&\textbf{Pilot}&\textbf{Time in Flight}&\textbf{Distance}\\\hline
\textbf{First Flight}&Orville&$12$~seconds&$37$~meters\\\hline
\textbf{Longest Flight}&Wilbur&$59$~seconds&$260$~meters\\\hline
\end{tabular}

The average speed for the first flight was $x$ meters per second. The average speed for the longest flight was $y$ meters per second. What is the average of $x$ and $y?$ Express your answer as a decimal to the nearest tenth.
The average speed is defined as distance of flight divided by time in flight. Thus, $x$ is equal to $$\frac{37 \text{ meters}}{12 \text{ seconds}} \approx 3.083 \frac{\text{m}}{\text{s}}$$ and $y$ is equal to $$\frac{260 \text{ meters}}{59 \text{ seconds}} \approx 4.407 \frac{\text{m}}{\text{s}}.$$ The average of $x$ and $y$ is defined as $$\frac{x+y}{2}\approx\frac{3.083+4.407}{2}=3.745.$$ Rounding the answer to the nearest tenth, we have $3.7.$
