Problem
On December at Kitty Hawk, N.C., the Wright Flyer became the first powered, heavier-than-air machine to achieve controlled, sustained flight with a pilot aboard.
\begin{array}[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{array}
The average speed for the first flight was meters per second. The average speed for the longest flight was meters per second. What is the average of and Express your answer as a decimal to the nearest tenth.

The average speed for the first flight was meters per second. The average speed for the longest flight was meters per second. What is the average of and Express your answer as a decimal to the nearest tenth.
Solution
The average speed is defined as distance of flight divided by time in flight. Thus, is equal to and is equal to The average of and is defined as Rounding the answer to the nearest tenth, we have
Final answer
3.7
