Neil A. Armstrong was the first person ever to walk on the moon. After his historic landing on July 20, 1969, he stepped onto the moon's surface and spoke the famous phrase, “That's one small step for a man, one giant leap for mankind.”

His craft, Apollo 11, traveled $238,900$ miles from Earth to reach the moon. How many feet was this? Express your answer in both standard form and in scientific notation. Round your decimal to the nearest hundredth. (Note: There are $5280$ feet in each mile.)

Convert miles to feet.

$1,261,392,000\ \text{ft}$
