Answer: he fly 107.76 miles per hour for each hour
Step-by-step explanation:
Charles Lendbergh had his first solo flight across the Atlantic Ocean. He flew 3,610 miles in 33.5 hours.
Speed = distance /time
If he flew about the same number of miles each hour, it means that the number of miles that he flies in each hour would be
3610/33.5
= 107.76.miles per hour.
3.5 · 10⁻² · 2.64 · 10²⁰
= 3.5 · 2.64 · 10²⁰⁻²
= 9.24 · 10¹⁸
