The first flight was given as 120 feet in 12 seconds. Doing the math
![((120)/(5280) )/((12)/(3600) )](https://img.qammunity.org/2023/formulas/advanced-placement-ap/high-school/gp8id9nycj3llqp8ok0fygqyztt5lbwid4.png)
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.
