Answer:

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.

Explanation:

She will run x kilometers.

She has already run 5/8 of the distance(5/8 of x), and still needs to run 75 kilometers.

So


(5x)/(8) + 75 = x


x - (5x)/(8) = 75


(8x - 5x)/(8) = 75


3x = 8*75


x = (8*75)/(3)


x = 200

The athlete will run 200 kilometers.

A atleta percorrerá 200 quilômetros no total.
