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 = ![\frac{totaltime}{number of hot dogs eaten}](https://tex.z-dn.net/?f=%5Cfrac%7Btotaltime%7D%7Bnumber%20of%20hot%20dogs%20eaten%7D)
We get;
![\frac{15x}{x+24} =7.5](https://tex.z-dn.net/?f=%5Cfrac%7B15x%7D%7Bx%2B24%7D%20%3D7.5)
![(x+24)7.5=15x](https://tex.z-dn.net/?f=%28x%2B24%297.5%3D15x)
![7.5x+180=15x](https://tex.z-dn.net/?f=7.5x%2B180%3D15x)
![7.5x=180](https://tex.z-dn.net/?f=7.5x%3D180)
x = 24 (third placer)
And the winner consumed
hot dogs.
Y/9=44/54
9(Y/9)=9(44/54)
Y=7 1/3 or 22/3
