Answer:

7th Place

Step-by-step explanation:

Seeing as how the number of runners in front of Paula is [tex]\frac{1}{3}[/tex] the number of runners behind her,

Assign the number of people behind Paula to a variable:

# of people behind Paula = b, which means

# of people ahead of Paula = [tex]\frac{1}{3}[/tex] b

Use the variable to make an equation:

b (people behind Paula) + [tex]\frac{1}{3}[/tex] b (people ahead of Paula) + 1 (Paula) = 25

b + [tex]\frac{1}{3}[/tex] b + 1 = 25

Solve for b:

b + [tex]\frac{1}{3}[/tex] b + 1 = 25

b + [tex]\frac{1}{3}[/tex] b = 24

[tex]\frac{4}{3}[/tex] b = 24

b = 18

If there are 18 people behind Paula, there are [tex]\frac{1}{3}[/tex] * 18 people in front of her, which is 6; This puts Paula in 7th place.
