Pls help i really need it

i dont understand how to do it

Just remember that 1 mile is equal to 5,280 feet.

If we have 5 miles, we need to multiply it my 5,280 which would equal 26,400.

Then we have the other 529 feet that they gave. Just add 26,400ft and 529ft and they will equal 26,929 ft.

Hope it helped! Remember, five tomatoes! (five two eight oh(0)).

The third box is a function

Omg that is a big question and weird words and i’m only 5
