The third-place finisher of the Allen County hot dog eating contest, in which each contestant was given an equal amount of time to eat as many hot dogs as possible, required an average of 15 seconds to consume each hot dog. How many hot dogs did the winner eat?

(1) The winner consumed 24 more hot dogs than did the third-place finisher.

(2) The winner consumed hot dogs at double the rate of the third-place finisher.

1)

No hot dogs consumed by third placer=N3 = t *1/15

N3+24=t*r

insufficient.. we need to know the t or r

2)

N3= t*1/15

N1 = t*2/15

insuffcient

combined.

N1=2N3=N3+24

N3=24

N1=48

sufficient.
