Step-by-step explanation:
Given : Speed skiing takes place on a course that is [tex]\dfrac{2}{3}[/tex] mile long .
We know that one mile = 5280 feet
Then, [tex]\dfrac{2}{3}\text{ mile}=\dfrac{2}{3}\times5280=3520[/tex]
It means the length of the course = 3520 feet.
Hence, the course is 3520 feet long.
