Answer:
Third placer consumed 24 hot dogs.
Winner consumed 48 hot dogs.
Step-by-step explanation:
Lets assume that the third runner up eats x hot dogs.
The total time for the contest is 15x seconds.
Given is that the winner ate (x+24) hot dogs
The winner's rate of eating is 1 hot dog per 7.5 seconds.
And we know the rate = [tex]\frac{totaltime}{number of hot dogs eaten}[/tex]
We get;
[tex]\frac{15x}{x+24} =7.5[/tex]
[tex](x+24)7.5=15x[/tex]
[tex]7.5x+180=15x[/tex]
[tex]7.5x=180[/tex]
x = 24 (third placer)
And the winner consumed [tex]24+24=48[/tex] hot dogs.
