Question

What was the average speed of the first flight of a powered airplane?

Answer 1

Answer:

Explanation:

Comment

The first flight was given as 120 feet in 12 seconds. Doing the math

$\dfrac{\dfrac{120}{5280} }{\dfrac{12}{3600} }$

gives 6.82 miles / hour

But the history of what made this flight possible was an engineering act of very careful experimentation and a great deal of thought on how to use mathematics to solve flight problems. It's worth looking up.

Answer 2

Answer:

I think the average speed is  6.8  miles per hour
