First flight,  Orvile 12 seconds, 37 meters.

Longest flight, Wilbur, 59 seconds, 260 meters.

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.

$$x=\frac{37m}{12s}=3.08\overline{3}m/s\\ y=\frac{260m}{59s}=4.407m/s$$

$$\frac{x+y}{2}=\frac{(3.083+4.407)m/s}{2}\approx 3.7m/s$$
